François Naftali Frenkiel (Warsaw, 19 September 1910 – Rockville, Maryland, 9 July 1986) was a physicist and one of the founders of the American Institute of Physics (AIP) journal Physics of Fluids in 1958.
François Frenkiel, received his undergraduate education in Mechanical and Aeronautical Engineering at the University of Ghent, Belgium, and his Ph.D. in physics from the University of Lille in France where he studied under the direction of Kampé de Fériet.
Naval Ordnance Laboratory, the Johns Hopkins University Applied Physics Laboratory and, from 1960 until his retirement, with the David W. Taylor Naval Ship Research and Development Center.
In addition to being the founder and longtime editor of Physics of Fluids, he served on a large number of national and international committees, e.g., to name but a few, the International Union of Theoretical and Applied Mechanics (IUTAM), the U.S. National Committee on Theoretical and Applied Mechanics, and the Division of Fluid Dynamics of the American Physical Society of which he was the chairman and secretary on numerous occasions.
He published extensively in the field of turbulent flows and pioneered the application of high-speed digital computing methods to the measurement of turbulence and the mathematical modeling of urban pollution.
