Dr Turgut 'Sarp' Sarpkaya is Distinguished Professor at the US Naval Postgraduate School, Monterey, CA. He is an internationally recognized authority in fluid mechanics research and was named by Cambridge University as one of the world's one thousand greatest scientists. 'Sarp', as he is known to friends and colleagues, is the recipient of the Turning Goals into Reality Award by NASA, and he was selected Freeman Scholar by the American Society of Mechanical Engineers. Sarpkaya received his PhD from the University of Iowa, followed by postdoctoral work at MIT. He was the Thomas L. Fawick Distinguished Professor at the University of Nebraska and taught at the University of Manchester. He was named Professor and Chairman of Mechanical Engineering at the Naval Postgraduate School in 1967 and Distinguished Professor in 1975. His research over the past 50 years has covered the spectrum of hydrodynamics. His oscillating flow tunnel and the vortex-breakdown apparatus are two among several unique research facilities he has designed. Sarpkaya has published more than 200 papers and has explored for the Defense Advanced Research Projects Agency (DARPA) numerous classified projects dealing with the hydrodynamics and hydroacoustics of submarines. He served as chairman of the Executive Committee of the Fluids Engineering Division of the American Society of Mechanical Engineers (ASME) and the Heat Transfer and Fluid Mechanics Institute. He is a Fellow of the Royal Society of Naval Architects and Marine Engineers, Fellow of the ASME, and Associate Fellow of the American Institute of Aeronautics and Astronautics.
