Paul Cooper Presentation Title: The Future of Pumping Machinery Abstract: Rotodynamic pumps are the most ubiquitous form of centrifugal turbomachinery. Together, they command huge expenditures of energy and human effort to operate and maintain. Acknowledging historic, existing operating inefficiencies and reliability issues highlights the need for a paradigm shift in the design of these machines that would yield major reductions in energy consumption and the cost of maintenance. Separated flows and many cavitating flows can be virtually eliminated through CFD-aided fluid dynamical design coupled with the pervasive adoption of variable geometry and rotative speed, both of which are continuously matched to changing system demands. New motor technology and controllability are key to reaping the benefits of these supposedly daunting design solutions. Existing machines with some of these features include hydraulic turbines and compact sealed pump-and-driver sets, and these point to one of the major areas for the fluids engineering community to participate in the emerging generation's inexorable march toward the greener and more productive environment of the future. Biography: Paul Cooper has spent 50 years in the pump industry, first in the fluid dynamical design of aircraft fuel pumps and inducers for TRW, then in R&D on hydraulics and cavitation for the Flowserve Corporation. His designs and ideas have been incorporated into many centrifugal and rotary pumps and turbines. He remains active in the fluid machinery field as a consultant. Dr. Cooper holds a B.S. in M.E. degree from Drexel University, an M.S. in M.E. from Massachusetts Institute of Technology, and a Ph.D. from Case Western Reserve University. He is a Life Fellow of the ASME, a recipient of society's Henry R. Worthington Medal for achievement in the field of pumping machinery, its Fluid Machinery Design Award, and its Fluids Engineering Award. He has lectured extensively, has written many papers, is co-editor of the Pump Handbook, and holds several patents.
