Budugur Lakshminarayana Deceased, 2001 Evan Pugh Professor of Aerospace Engineering director, Center for Gas Turbines and Power; Ph.D. (1963 and D. Eng. (1981), University of Liverpool

Dr. Lakshminarayana has more than thirty years of teaching, research, and consulting experience in turbomachinery aerodynamics, computational and experimental fuild dynamics, aerospace propulsion, gas turbines, turbulence modeling, and aeroacoustics. Most of his research is directed toward detailed understanding and modeling of the flow field in turbomachines. The specific areas include tip clearance efforts, rotor wakes, spanwise mixing, secondary flow, loss mechanisms and three-dimensional steady and unsteady flow field in both single and multistage turbomachinery, marine propulsors, rocket pump inducers, and automotive torque converters. The computational efforts include unsteady flow and noise generated in aircraft compressors and turbines; rotor-stator interaction; marine propulsors and unsteady transition and bourndary layer growth in turbines; steady flow field in rocket turbomachinery; high temperature flows; turbulence modeling for curvature, rotation, and thermal effects; and heat transfer in turbines. His experience covers a wide spectrum including experimental work, analytical and computational modleing, and improvement in turbomachinery performance through loss correlactions. He was instrumental in developing the turbomachinery laboratory at Penn State, which now comprises a multistage compressor facility, axial flow turbine facility, single-stage compressor facility, and a torque converter facility.

Dr. Lakshminarayana is a Fellow of AIAA and ASME. He has most recently been honored with the AIAA Air Breathing Propulsion Award and advisory professorships from the Shangai Jaio Tong University and the Chinese Academy of Sciences, Institute of Engineering Thermophysics in Beijing. He has received numerous other awards including the Arch T. Colwell Merit Award (SAE), ASME Freeman Scholar Award, AIAA Pendrey Aerospace Literature Award, NSF International Award for Scientists, CNRS Professorship at Ecole Centrale de Lyon (France), Fulbright Senior Professor Award for Research in Germany, and Distinguished Alumni Professor and Premier Research Awards From Penn State.
