"Advances in Turbines Aero-thermo-mechanical Design and Analysis"
Saturday & Sunday, June 9 & 10, 2012
Bella Convention & Exhibition Center
Copenhagen, Denmark
Overview and Objective
The present multidisciplinary Lecture Series addresses the current state of the art in the design and analysis of axial turbines. Both aerodynamic, heat transfer and mechanical concepts are developed by authors coming from industry, governmental and research agencies and universities. Earn
14 Professional Development Hours (PDH’s) and receive a certificate
of completion!
Topics of Discussion
- The first lecture will explain the successive steps of the aero-design of high-pressure turbines. Future improvements in the performance of turbine based propulsion largely depend on our understanding of unsteady flows.
- In view of decreasing weight and costs, current turbomachinery designs tend to increase the stage loading and to shorten the distance between blade rows. Several consecutive courses are dedicated to unsteady effects in HP turbines, LP turbines.
- Turbine tip clearance improvement, in spite of known challenges, continues to present one of the most powerful means for enhancement of gas turbine engine performance. The experimental and numerical study of various tip configurations will be addressed as well. An overview of film cooling for the turbine will also be provided given the prevailing needs for technology improvement in this area.
- Sessions on forced response address the impact of the excitation on blade and disk vibrations. Current practice of aeromechanical design are presented and illustrated with practical examples in turbines.
- Design strategies to mitigate unsteady forcing presents a successful example of resonant-stress reduction through mitigation of unsteady forcing during the aerodynamic design of turbine components.
- The final lecture will present applications to control the flow in turbines, their performance is evaluated using Large Eddy Simulations.
After completing the course the participants should be able to:
- Understand the aerodesign process of high pressure turbines
- Identify the relevance of unsteadiness in low pressure and high pressure
turbines
- List techniques to refrigerate the turbine tip
- Identify the process to evaluate the force response
Who Should Attend
The course is aimed at Turbomachinery designers, as well as experimental
and CFD aero-thermal scientists.

Instructors
Dr. Ron Bunker is a Principal Engineer at the GE Global Research Center in Niskayuna, NY. He is an internationally recognized research engineer in the field of Gas Turbine Heat Transfer. He has been performing and directing research related to all aspects of turbine hot gas path heat transfer and cooling for the past 25 years. Dr. Bunker is a Fellow of the American Society of Mechanical Engineers, and Chair of the Board of Directors of the International Gas Turbine Institute. Dr. Bunker has been awarded 54 US patents, with 40 more pending, all dealing with gas turbine and power technologies. Dr. Bunker is also the author of over 100 technical publications and refereed papers, and more than 150 internal company reports.
Dr. John Clark is the Lead for Turbine Component Research in the Turbine Engine Division of the Propulsion Directorate, Air Force Research Laboratory. He received his doctorate in Engineering Science from the University of Oxford and he has over 20 years of experience in turbine aero-thermal design, analysis, and experimentation. This includes industrial experience from the turbine aerodynamics group at Pratt & Whitney. He has received two patents and has a third pending. He is particularly interested in design techniques to reduce levels of unsteady forcing that occur in transonic turbines, and that is the focus of his lecture in this course.
Dr. Frank Haselbach is heading turbine aerothermal design globally in the Rolls-Royce group. He is an expert in high-pressure and low-pressure turbine design and operation and a Rolls-Royce engineering fellow for Turbine Aerothermal. Before settling in the UK in 2005, Frank managed turbine aero/cooling in Germany, RRD (Berlin) and lectured compressible flow at the University of Berlin. Frank is owner of three international patents on turbine design and author of more than 40 journal and technical articles on turbine design and instrumentation. Frank now lives with his wife and two daughters in Southern Derbyshire, UK.
Dr. Howard Hodson holds the Chair of Aerothermal Technology at the Whittle Laboratory, University of Cambridge. He is a Fellow of the Royal Academy of Engineering, the American Society of Mechanical Engineers and. the Royal Aeronautical Society. He has recently served as Chair of the Turbomachinery Committee of the IGTI and he is an incoming member of the IGTI Board. He has been active in the field of turbine aerodynamics for more than 30 years and has published over 100 journal papers. His current research interests include blade design, unsteady flow effects and laminar-turbulent transition in Low Pressure Turbines, the results of which will form the basis of his lecture on this course.
Dr. Guillermo Paniagua is Associate Professor, Turbomachinery & Propulsion Dept., von Karman Institute for Fluid Dynamics and visiting Professor at the University of Valencia. He has 12 years of experience on aero-thermal research on high pressure turbines, for which he has been awarded three international prizes and a patent. In recent years he is also involved in high speed propulsion and boundary layer transition research.
Dr. Eric Seinturier is Chief Engineer for Research and Technology at Turbomeca. He graduated from French National Institute of Applied Sciences in 94 (INSA Lyon). After 3 years in the nuclear field in accidental behaviour simulation,
he joined Snecma in 1998 as research project manager for Aeroelasticity and bladed disks vibrations. He arrived at Turbomeca in 2004.
