Track #3 - Combustion Science and Engineering
 
  Plenary Speaker: Robert Brown, Iowa State University, Ames, IA


Presentation Title: Pyrolysis Energy Systems


Biography: Dr. Brown is Anson Marston Distinguished Professor of Engineering and Gary and Donna Hoover Chair in Mechanical Engineering at Iowa State University (ISU). He also holds courtesy academic appointments in the Departments of Chemical and Biological Engineering and Agriculture and Biosystems Engineering. He is the director of ISU's Bioeconomy Institute.

Dr. Brown is the Director of the Bioeconomy Institute, which coordinates research, education, and extension in bioenergy and biobased products at ISU. He has published the textbook Biorenewable Resources: Engineering New Products from Agriculture and helped establish at ISU the first graduate program in the United States to offer degrees in biorenewable resources. Dr. Brown is a Fellow of the American Society of Mechanical Engineering and Distinguished Iowa Scientist of the Iowa Academy of Science.


Abstract: Pyrolysis is the thermal conversion of carbonaceous materials in the absence of molecular oxygen to liquids, solids and gases. The liquids, known as bio-oil, have applications ranging from power generation, transportation fuels, and production of commodity chemicals. The solid co-product, known as biochar, also can be used for power applications but more intriguing applications include carbon sequestration and soil amendment. The gas, a mixture of carbon monoxide, methane, and hydrogen, is most commonly used to heat the pyrolysis process.


In the most general sense, pyrolysis can occur in an inert or reducing atmosphere or within a solvent (including water); it can occur at atmospheric or elevated pressure; heating rates can be as slow as hours or as fast as seconds; and it can occur in the presence or absence of catalysts. Much of the attention has focused on fast pyrolysis, which produces liquid (bio-oil) as the major product (75 wt%). Bio-oil is a mixture of water and oxygenated organic compounds that can be upgraded to synthetic gasoline and diesel fuel. However, prominent shortcomings of bio-oil, including poor stability and corrosiveness, have encouraged investigations of other kinds of pyrolysis for the production of hydrocarbon fuels, including catalytic pyrolysis; hydropyrolysis (pyrolysis in presence of hydrogen); and solvent liquefaction (pyrolysis in the presence of a solvent). The goal of these alternative approaches to conventional fast pyrolysis is to produce less oxygenated molecules, which will improve stability and suitability of the resulting "renewable crude" as refinery feedstock.


Traditional fast pyrolysis produces bio-oil containing hundreds of compounds dominated by small oxygenates arising from the decomposition of cellulose and hemicellulose and large phenolic oligomers derived from lignin (so-called pyrolytic lignin). Neither the light ends nor the heavy ends are particularly well suited for efficient upgrading of bio-oil to hydrocarbon fuels. Deoxygenation of the light ends produces many hydrocarbons that are too volatile for liquid fuels. Cracking of the viscous heavy ends often results in unacceptable levels of coking. The result is relatively low yields of fuel range hydrocarbons.


This talk will review a variety of pyrolysis processes and discuss promising applications of pyrolysis products. Also to be presented is recent research that suggests pyrolysis could be used to convert cellulosic biomass into sugars.

 
    Plenary Speaker: David Tillman, Retired Chief Fuels and Combustion Engineer, Foster Wheeler North America


Presentation Title: Biomass Cofiring-Results of Research Programs Related to Demonstrations


Biography: Dr. David A. Tillman has distinguished himself as an international expert in the areas of fuels, combustion, and incineration, primarily as Chief Engineer and Consultant for Foster-Wheeler North America. He has worked with most of the major utility companies in North America and Europe, leading the development and commercialization of new and improved processes and equipment for coal and biomass combustion, with focus in biomass utilization, co-firing, and fuel blending. Dr. Tillman has also published extensively in books, journals, and conference proceedings, and has written several key reports for the Electrical Power Research Institute (EPRI).


Abstract: Biomass demonstrations, focusing on cofiring these renewable fuels in coal-fired boilers, have been technically successful in providing dispatchable renewable power while reducing airborne emissions. Results of full scale demonstrations at the Seward Generating Station of GPU Genco (now Reliant Energy), Albright Generating Station of Allegheny Energy LLC (now First Energy), and numerous other power plants showed a disproportionate reduction in NOx emissions while reducing SO2 and HAPS emissions as well. Recent research into the kinetics of combustion processes applied to biomass-coal blends, and research into burning profiles of parent fuels and blends, has provided key insights into the combustion processes associated with cofiring and the practical benefits of such processes. At the same time there are certain anomalies in the results that can now be more readily explained. This research parallels, and is supported by additional kinetics research into combustion processes blending highly reactive Powder River Basin subbituminous coals with Central Appalachian bituminous coals. Those parallels will be shown. Additional research concerning petroleum coke will also be shown. Commentary will also be given on the consequences of biomass-coal blending with respect to deposition and corrosion; particular attention will be given to sources and fates of chlorine, and methods to manage these issues through fuel blending.

Abstract: It is critical time to solve the problems of current qualitative biomedical science and healthcare system. In the first part of lecture, I will discuss nanosatellites that have multiple functions in living systems: targeting, imaging, gene delivery and gene regulations. Magnetic nanosatellites are being developed as new classes of smart MRI contrast agents, molecular diagnostic probes, magnetic cell labeling and separation tools. New paradigm of molecular optogenetics by nanosatellites is not only for the on-demand remote optical control of gene regulations, but also to create transcriptional pulses for digital biology and translational medicine. Molecular imaging by wireless nanosatellites provide us a new opportunity to explore inner life of living cells for understanding signaling pathways and cellular dynamics. Capturing the dynamics of epigenetic landscape via nanosatellites might give us insights for the rational cell reprogramming in regenerative medicine.


In the second part of lecture, I will discuss my vision for precision biology and preventive personalized medicine via cellular Biologic Application Specific Integrated Circuits (BASICs). As an example of BASICs, I will present a Self-powered Integrated Microfluidic Blood Analysis System (SIMBAS) that does not require any external connections, tethers, or tubing to deliver and analyze a raw whole-blood sample. By integrating these cellular BASICs platforms and nanoplasmonic optical antenna array, we are developing Optofluidic Application Specific Integrated System (OASIS) for label-free bioassays. The OASIS platform allows highly multiplexed nucleic acid and protein analysis for integrative molecular diagnostic systems. In summary, I will discus the convergence of science, engineering, and medicine to find the solutions for translational medicine and low-cost healthcare systems.

 
Track #6 - Microsystems Integration
 
    Plenary Speaker: Terry Ericsen, Office of Naval Research, Arlington, VA


Presentation Title: IMECE2011-62027 "Future of Power Electronics and Energy: an ONR Perspective"


Abstract: Over the next 10 years, shipboard power system will become highly integrated with increased voltage, power density, and switching speed. 440V is mainstay of today marine electrical power systems. Next generation systems will be 13.8KV AC prime power and 20kV DC distribution. High voltage and high frequency power semiconductors, capacitors, inductor, and transformers are needed. Packages for these components need to be compact with improved dv/dt, cooling, thermal cycling, and reliability.


New ship concepts such as the Electric Surface Combatant (ESC) will drive component technology. ESC Power will transfer power from propulsion to weapons, from non-critical loads to high power sensors, and from all ship systems to critical defense needs -"Scotty, more power to the shields." ESC Power will use equipment with 3x increase in power density. ESC Power will increase voltage to 13.8kV AV prime power with 20kV DC Medium Voltage DC (MVDC) distribution - enabling up to 30x increased system power density in future systems over existing 440v AC systems with increased efficiency and fuel savings. MVDC will enable the elimination of many tradition system components further increasing power density and efficiency.


ESC Power will employ Bidirectional Power Converters and System Wide Controllers to enable loads and sources to supply and receive power from the system. MVDC will enable sources and loads to be electronically decoupled so that power can be freely exchanged in the system. Decoupling sources and loads from mechanical and electrical shackles will allow new opportunities to optimize sources and loads to further increase power density and efficiency - enabling insertion of alternative power sources. Silicon Carbide (SiC) power semiconductors will enable rapid system reconfiguration and control of power flow to the right load at the right time by pushing system control down from seconds and minutes to nanoseconds and microseconds. Rapid power control will enable sailor safe systems and increased survivability. Bidirectional power flow control will enable system wide energy storage with power regeneration to enable distributed energy storage from the whole system rather than from l ocal, lumped, storage solutions. Power conditioning infrastructure in future electric weapons and sensors could be reduced by 90% by using system wide energy storage.


New design, development, and deployment tools will be used to enable a highly integrated engineering environment to reduce program cost. A new cloud based design environment will enable faster design evolution, more robust Analysis of Variance (ANOV), and vastly improved physical fidelity. Power in the Loop (PHL) and Hardware in the Loop (HIL) prototyping tools will decrease verification and validation time and increase the precision and accuracy of final system predictions leading to decreased development time and cost. New internet based concepts to connect PHL and HIL laboratories at University, Navy Labs, Navy Vendors, and Shipbuilders will further increase precision, accuracy, and control over the development process further reducing cost and development time.

Abstract: Since the Stone Age, people have tried to reproduce the human appearance, functions, and intelligence using art and technology. Any aspect that represents our physical and intellectual being has been a subject of copying, mimicking and inspiration. Realistic humanlike robots and simulations are becoming possible due to recent surges in technology advances [Bar-Cohen and Breazeal, 2004]. Making such robots is part of the field of biologically inspired technologies - also known as biomimetics [Bar-Cohen 2005] - and it involves developing engineered systems that exhibit the appearance and behavior of biological systems. Robots with selectable characteristics and personality that are customized to our needs and with self-learning capability may become our household appliance or even companion and they may be used to perform hard to do and complex tasks. In enabling this technology such elements as artificial intelligence, muscles, vision, skin and others are increasingly improved. In this paper, making humanlike robots will be described with focus on the use of artificial muscles [Bar-Cohen, 2004].

Abstract: Clinical treatment of pulmonary hypertension (PH) in children has focused on the distal vasculature for the last 4 decades; yet, the disease remains associated with unacceptably high morbidity and mortality. Over the last 10 years, several faculty at the University of Colorado Denver, using a highly inter-disciplinary approach involving vascular biologists, clinical cardiologists and bioengineers, have re-focused attention on the fact that PH affects both proximal and distal components of the pulmonary vascular system, and have shown using coordinated human, animal, in vitro and imaging studies that upstream pulmonary arteries, once thought to be simply conduits, play an important role in disease progression and should be included in the clinical evaluation of the pediatric pulmonary hypertension patient.


This talk will focus on how bioengineers have contributed to this work through the coordinated and quantitative use of imaging, modeling, and biomechanics, applied over a wide range of dimensional scales, from cell to organism, and across multiple species, from rodents to ungulates to humans. The talk will end with a discussion of recent work around use of next-generation live-tissue optical imaging techniques to explore hypoxia-associated changes in structure-function relationships of the pulmonary arterial extra-cellular matrix.

  Plenary Speaker: Huiyang Li, Ansys


Biography: Dr. Huiying Li is a lead software developer at the FLUENT development team, ANSYS Inc, Lebanon, New Hampshire. Since 2001, she has been working on a number of different development projects in Fluent, such as porous media modeling, compressible liquid flows, second-order time schemes, Eulerian multiphase compressible flows, multiphase mass and heat transfer, cavitation, evaporation-condensation, boiling models, and general solver improvement. Prior to joining Fluent, she had worked as a senior research engineer in CFD Research Corporation, Huntsville, Alabama. The research areas included cavitation modeling, fluid-structure-electrostatics interactions, and simulation of flows in MEMS devices.


She was educated in China and England. She had a BS and MS in Aerospace Engineering, and got her PhD in 1995 at University of Manchester, Manchester, England. The research topic was Turbulence Modeling and Heat Transfer and the Applications in Turbo-machinery.


Abstract: Modeling of wall boiling and critical heat flux (CHF) is one of the most challenging tasks towards the development of a generalized multiphase computational fluid dynamics (CFD) model for boiling flow and heat transfer. Boiling is a complex phenomenon and most of the sub-models proposed so far account only partially for the relevant physics such as the onset of nucleate boiling (ONB), departure from nucleate boiling (DNB), critical heat flux and post dry-out. This situation is further complicated when considering critical heat flux conditions as flow regime transitions need to be taken into consideration. As a part of an ongoing effort on providing a comprehensive CFD tool for modeling boiling flow and heat transfer, the present work intends to address those problems and to simulate boiling and critical heat flux using an Eulerian multiphase boiling model.


The present paper concerns the development and validation of an Eulerian multiphase boiling model to predict boiling and critical heat flux within the general-purpose CFD solver FLUENT. The governing equations solved are generalized phase continuity, momentum and energy equations. Turbulence effects are accounted for using mixture, dispersed or per-phase multiphase turbulence models. Wall boiling phenomena are modeled using the baseline mechanistic nucleate boiling model, developed in Rensselaer Polytechnic Institute (RPI). Modifications have been introduced to the quenching heat flux model to achieve mesh-independent solutions. The influences of boiling model parameters have also been systematically investigated. To model non-equilibrium boiling and critical heat flux, the PRI model is extended to the departure from nucleate boiling by partitioning wall heat flux to both liquid and vapor phases and considering the existence of thin liquid wall film. Topological functions are introduced to consider the wall boiling regime transition from the nucleate boiling to critical heat flux, and the corresponding flow regime change from bubbly flows to mist flows. A range of sub-models are implemented to model the interfacial momentum, mass and heat transfer and turbulence-bubble interactions.


To validate the Eulerian multiphase boiling model, it has been used to predict nucleating boiling and critical heat flux in a range of 2D and 3D boiling flows. The examples presented in the paper include: (1). Nucleate boiling of sub-cooled water in an upward heated pipe; (2) R113 liquid flows through a vertical annulus with internal heated walls; (3). 3D boiling flows in a rectangular-sectioned duct; and (4). Critical heat flux and post dryout in vertical pipes. The results demonstrate that the model is able to predict reasonably well the distributions of wall temperature, the bulk fluid sub-cooling temperature and cross-sectional averaged vapor volume fraction in the vertical pipe. The computed profiles of the vapor volume fraction, liquid temperature, and the liquid and vapor velocity profiles are generally in good agreement with available experiments in the 2D annular case. In the 3D rectangular duct, the cross-sectional averaged vapor volume fractions are well captured in all the ten cases under investigation. In the case of critical heat flux and post dryout, the model is also able to predict reasonably well the location and the temperature rise under critical heat flux conditions. The computed wall temperature distributions along the pipes are in overall good agreement with available experiments.

Abstract: As of November 2010, 29 countries worldwide are operating 441 nuclear reactors for electricity generation and 65 new nuclear plants are under construction in 15 countries. Like wind and hydro-electricity, nuclear power has the lowest carbon footprint. Nuclear power plant costs about three times more than coal power plant. However the production cost of electricity is 50% less. President Barack Obama called for "a new generation of safe, clean nuclear power plants" in his 2010 State of the Union address and pledged to triple US nuclear investment. Following the Japanese quake and tsunami in March 2011 near Sendai, the Obama administration restated its support, with spokesman Jay Carney telling reporters that nuclear "remains a part of the President's overall energy plan". In terms of energy in an earthquake, each whole number increase in the Richter Scale corresponds to an increase of about 32 times the amount of energy released. In this presentation the basics of tsunami mechanics, earthquakes, nuclear fission, and accidents at the Fukushima Dai-ichi nuclear power plants, disaster mitigation, as well as research, challenges and safety of nuclear power plants are to be presented.

Presentation Title: IMECE2011-65986 "A Finite Element Method for Ablation Problems"


Abstract: Aerodynamic heating and ablation problems are common in the design and analysis of rocket nozzles and reentry bodies. One-dimensional computational simulations of the thermal response of these structures has often been adequate because of the relatively simple geometries employed. More complex geometries are becoming common and the thermal protection systems are subjected to more variability in thermal input and external flow fields. Most previous simulations considered only thermal conduction effects within the ablating material and neglected pyrolysis gas flow in the ablator. The present work considers a transient, fully three-dimensional approach to the simulation of material thermal response with ablation. The balance laws describing the solid/gas system for a porous ablator are discretized using a finite element method. General reaction kinetic mechanisms describing material decomposition (pyrolysis) are included at the element level. Surface recession of the ablator is coupled to the mechanics with a moving mesh formulation; a remeshing scheme is also considered for extremes in material deformation. Material regions subject to thermal conduction and enclosure radiation are also allowed and are fully coupled to the ablation region. Boundary conditions are general to accommodate all classes of aerodynamic heating and coupling with external flow codes. The utility of the approach is demonstrated with high-fidelity simulations of prototype geometries.

 
  Plenary Speaker: John Rudnicki, Northwestern University


Presentation Title: Formation and Extension of Localized Compaction in Porous Sandstones


Abstract: Narrow, roughly planar zones of localized porosity loss have been observed in porous sandstones both in the field and in the laboratory. In the laboratory the bands form perpendicular to the maximum compressive stress and are inferred to do so in the field. Although this mode of localization has been recognized only recently in porous rocks, it is common in a variety of other porous materials, e.g., cellular solids and metal foams. The significance of these compaction bands in sandstones is that both laboratory and field studies have shown that bands reduce the permeability by one to several orders of magnitude, and they form barriers to fluid flow. Consequently, their presence in subsurface formations would affect applications involving fluid injection or withdrawal, including sequestration of CO2 to mitigate adverse effects on the climate. This talk will summarize laboratory and field observations of compaction bands and discuss theoretical results for their formation and extension. Theoretical results for band formation based on localization theory are roughly in accord with laboratory observations although detailed quantitative comparison is limited by the simplicity of the models and available data. A simple model of a wedged “anti-crack” (same as a tensile crack with the sign reversed; interpenetration is interpreted as inelastic compaction) is consistent with field data indicating that the midpoint width of the band scales as the square root of the band half-length. Although the microstructures of bands in the field and in the laboratory are different, estimates of a critical compactive energy release rate from field observations is comparable to those inferred from nominal stress strain curves of notched laboratory specimens. Micro-computed tomography images of a sandstone core from the field have revealed an increase in occluded pore space and tortuosity within the band. Upscaling methods indicate a permeability reduction of about an order of magnitude, less than suggested previously.

Track #13- Dynamic Systems and Control
 
  Plenary Speaker: Marco Amabili, McGill University


Presentation Title: New Results on Nonlinear Vibrations and Stability of Shells


Biography: Graduating summa cum laude with a Master’s degree in Mechanical Engineering from the University of Ancona, Italy in 1992 and completing his PhD in Mechanical Engineering, with a specialization in Vibrations at the University of Bologna, Italy in 1995, Marco Amabili currently is Full Professor in the Department of Mechanical Engineering at McGill University, Montreal, Canada, where he has held a prestigious Canada Research Chair, Tier 1. Prior to joining McGill, Professor Amabili held positions of Assistant and Associate Professor at the University of Parma, Italy. Professor Amabili’s area of research focuses on nonlinear vibrations and stability of shells and plates and fluid-structure interaction. He developed an innovative nonlinear higher-order shear deformation theory for laminated shells and extensively worked on reduced-order models to study nonlinear vibrations and stability of shells and plates. He serves as Chair of the ASME Technical Committee on Dynamics and Control of Systems and Structures (AMD division). He is Associate Editor of Journal of Fluids and Structures (Elsevier), Applied Mechanics Reviews (ASME), Mechanics Based Design of Structures and Machines (Taylor & Francis). He is Member of the Editorial Board of Journal of Sound and Vibration (Elsevier) and International Journal of Structural Stability and Dynamics (World Scientific). He has written 110 journal papers, 150 conference papers and the book published by Cambridge University Press “Nonlinear vibrations and stability of shells and plates”.


Abstract: Because of the optimal distribution of material, shells collapse for buckling much before the failure strength of the material is reached. For their thin nature, they can present large displacements, with respect to the shell thickness, associated to small strains before collapse. This is the rationale for using a geometrically nonlinear shell theory for studying shell stability. Shells are often subjected to dynamic loads that cause vibrations; vibration amplitudes of the order of the shell thickness can be easily reached in many applications. In these cases, a nonlinear shell theory should be applied. Large-amplitude (geometrically nonlinear) vibrations of isotropic, laminated and FGM shells with different boundary conditions and subjected to harmonic excitation are discussed. Both numerical and experimental results will be shown and compared. Simple and advanced shell theories are used to calculate the elastic strain energy. In-plane inertia and geometric imperfections are taken into account. The solution is obtained by the Lagrangian approach. Reduced-order models based on the proper orthogonal decomposition method (POD) and asymptotic nonlinear normal modes (NNMs) are discussed and compared. Internal resonances are also studied. The nonlinear shell dynamics is investigated by using the pseudo-arclength continuation method, bifurcation analysis, bifurcation diagrams obtained by direct time integration, and calculation of the Lyapunov exponents. Interesting phenomena such as (i) snap-through instability, (ii) subharmonic response, (iii) period doubling bifurcations, (iv) chaotic behavior, and (v) hyperchaos are observed. Applications are addressed.

Abstract: Sustainable manufacturing has been recognized as the driver for innovation in the manufacturing industrial sector. Sustainable manufacturing involves the creation (design and manufacturing) of products using processes that minimize negative environmental impacts, conserve energy and natural resources, are safe for employees, communities, and consumers and are economically sound. Sustainable manufacturing challenges are illustrated through the recently introduced 6R methodology (Reduce, Reuse and Recycle, Recover, Redesign and Remanufacture). This includes consideration of total life-cycle involving four major life-cycle stages (pre-manufacturing, manufacturing, use and post-use) for manufactured products, and the associated manufacturing processes. A case study will be presented to show how sustainable products can be produced from sustainable manufacturing processes with demonstrated biomedical applications. This case study involves sustainable cryogenic machining and burnishing processes performed on two selected biomaterials (Co-Cr-Mo and AZ31B Mg alloys) for achieving enhanced product performance and life for use in biomedical implants. This study shows that surface integrity, involving severe plastic deformation (SPD), induced by cryogenic machining and burnishing processes, is significantly improved with performance enhancement through controllable ultra-fine/nano grain structures and the associated wear and corrosion resistance properties and the generation of compressive residual stresses enabling improved fatigue life in the machined and burnished biomaterials. Experimental results are compared with numerical/analytical simulations.

Track #20- Applied Stochastic Optimization, Uncertainty and Probability
 
  Plenary Speaker: Michael Beer, University of Liverpool


Presentation Title: IMECE2011-65908 "Imprecise Probabilities in Engineering"


Abstract: Uncertainty and imprecision in structural parameters and in environmental conditions and loads are challenging phenomena in engineering analyses. They require an appropriate mathematical modeling and quantification to obtain realistic results when predicting the behavior and reliability of engineering structures and systems. But the modeling and quantification is complicated by the characteristics of the available information, which involves, for example, sparse data, poor measurements and subjective information. This raises the question whether the available information is sufficient for a probabilistic modeling or rather suggests a set-theoretical modeling. The framework of imprecise probabilities provides a mathematical basis to deal with these problems which involve both probabilistic and non-probabilistic characteristics of information. A common feature of the various concepts of imprecise probabilities is the consideration of an entire set of probabilistic models in one analysis. But there are differences between the concepts in the mathematical description of this set and in the theoretical connection to the probabilistic models involved. This lecture provides an overview on selected concepts of imprecise probabilities, which are increasingly adopted for the solution of engineering problems. Specific features and relationships between the models are discussed. Particular attention is devoted to the concept of fuzzy probabilities. Examples of applications in engineering underline the usefulness of the concepts discussed.

Biography: Xi Frank Xu was born in Jianyang, Fujian of China in 1971. With a Bachelor degree from Tsinghua University in 1993, he had practiced as a structural engineer for 5 years in Shanghai before returning to graduate school. He received his PhD in civil engineering from Johns Hopkins in 2005 and since then has been serving as an assistant professor at Stevens Institute of Technology. His research interests cover a broad range of topics on multiscale & stochastic modeling of complex engineering systems, including synthetic materials (composites, metamaterials, concrete, polycrystals), natural materials (soils, rocks, biomaterials), and natural hazards (earthquake, wind, flooding). The honors he received include the Distinction Graduation Honor from the Robert Gordon University, Scotland, in 1999, the Meyerhoff Fellow from the Johns Hopkins University in 2001, the finalist honor in the 17th Annual Robert J. Melosh Competition for the Best Student Paper in Finite Element Analysis in 2005, the Early Career Principle Investigator Award from the US Department of Energy in 2006, and the 2010 K.J. Bathe Award for the Best Paper by a Young Researcher in the Field of Computational Engineering.


Abstract: Conventional uncertainty quantification (UQ) methods have been prevalently formulated with a random variable representation of uncertainties for both inputs and outputs through physical, chemical, or biochemical systems normally described by differential equations. In assessing performance certification of engineering systems, the output parameter or index is usually a nonlinear functional of the input random processes, such as environmental impacts (temperature, wind, humidity) on energy efficiency of buildings and industrial facilities. Due to exponential increase of random dimensions in nonlinear propagation of uncertainties, the random variable based UQ methods are by nature subjected to the curse-of-dimensionality issue. In [1,4], by constructing an orthogonal functional space about an underlying random process in time or random field in space, a novel random field based orthogonal expansion (RF-OE) method is proposed, which opens a new direction to break the curse-of-dimensionality in stochastic computation. By applying the RF-OE method and variational principles [3], a Green-function-based multiscale stochastic finite element method (MSFEM) is formulated in [2] for solid mechanics computation of random composites. In [4,5] the EF-OE method is further applied to random media problems and stochastic problems. It is expected the novel representation of uncertainties using orthogonal expansions of random processes will enable fast computations of many complex systems that otherwise infeasible based on conventional UQ methods, with a broad range of engineering applications on reservoir modeling (carbon sequestration), contaminant transport, and nuclear waste repository, life-cycle prediction of materials (fatigue), etc.
