Short Bio

Fellow of the American Physical Society, Fellow of the American Institute for Aeronautics and Astronautics (AIAA), Fellow of the American Society of Mechanical Engineers (ASME), Fellow of the Australasian Fluid Mechanics Society, Fellow of the American Association for the Advancement of Science, Member of the National Academy of Engineering.  He is a Professorial Fellow at Monash University in Melbourne, Australia.

Dr. Smits’s research interests are centered on fundamental, experimental research in turbulence and fluid mechanics. Particular aspects include Reynolds numbers scaling of turbulent flows, the effects of roughness; bio-inspired propulsion; drag reduction using liquid-infused porous surfaces; the behavior of turbulent flows at supersonic and hypersonic speeds; vertical axis wind turbine aerodynamics; sports ball aerodynamics, and the development of new and improved measurement techniques.

He is the co-author (with J.P. Dussauge) of “Turbulent Shear Layers in Compressible Flow,” Springer-Verlag, 1996 (2nd edition, 2005), author of “A Physical Introduction to Fluid Mechanics,” John Wiley & Sons, 2000, and co-editor (with T.T. Lim) of “Flow Visualization: Techniques and Examples,” Imperial College Press, 2000 (2nd edition, 2011), as well as the author or co-author of more than 300 journal articles and papers in conference proceedings. He holds patents on testing the aerodynamics of golf balls, and on using femtosecond lasers in eye surgery and tattoo removal.  Dr. Smits received the Aerodynamic Measurement Technology Award from AIAA in 2014, and an Honorary Doctorate of Engineering from University of Melbourne in Australia, in 2011. In 2009, he received the Médaille de la Ville de Marseille. In 2007, he received the Fluids Engineering Award from the ASME, and the Pendray Aerospace Literature Award from the AIAA, as well as the President's Award for Distinguished Teaching from Princeton University. In 2004, Dr. Smits received the Fluid Dynamics Award of the AIAA. He was the Chair of the Division of Fluid Dynamics of the American Physical Society in 2007-2008. He is currently the Editor-in-Chief of the AIAA Journal, an Associate Editor of the Journal of Turbulence, and he is on the Editorial Board of the Journal of Sports Engineering and Technology. He is a past Associate Editor of the Journal of Fluid Mechanics and Physics of Fluids. From 1995 to 1999, he served as Editor-in-Chief for the Journal of Experimental and Thermal Fluid Science, and he is a Chief Editor,, a specialty web portal for students and researchers in fluid dynamics.
