Uriel Frisch

Uriel Frisch (born December 10, 1940 in Agen ) is a French applied mathematician who deals in particular with turbulence .

Frisch studied from 1959 to 1963 at the École normal supérieure , graduated in 1962 (licentiate) in applied mathematics from the University of Paris and received his doctorate there in 1964 (These de troisieme cycle) and 1967 (These d´Etat). From 1963 he was a scientist at the CNRS in Paris and from the 1990s at the University of Nice , meanwhile as emeritus research director at the Labor Cassiopèe in Nice. In 1966/67 he was at the Courant Institute of Mathematical Sciences of New York University and in 1978/79 he was visiting professor at Harvard University .

Uriel Frisch deals mathematically and numerically with hydrodynamics and magnetohydrodynamics as well as with nonlinear dynamics (such as intermittency in chaos theory ) and statistical physics with applications in geophysics, astrophysics and cosmology. In 1986 he showed with Brosl Hasslacher and Yves Pomeau (at that time at Los Alamos National Laboratory ) that a simple cellular automaton with simple conservation laws on a microscopic level can simulate the entire complexity of the Navier-Stokes equations of hydrodynamics (Lattice Gas Cellular Automata, LGCA, also FHP model according to the authors, from this later the Lattice Boltzmann Equation, LBE) developed. To do this, they had to use hexagonal grids.

In 1967 he received the Peccot Prize of the Collège de France for his dissertation . In 1985 he received the Bazin Prize from the Académie des Sciences , of which he has been a member since 2008. In 2003 he received the Lewis Fry Richardson Medal from the European Geophysical Society. In 1994 he became Chevalier Ordre national du Mérite . In 2010 he received the International Prize for Applied Mechanics Modesto Panetti e Carlo Ferrari of the Turin Academy.
