Grigory Isaakovich Barenblatt (Григо́рий Исаа́кович Баренблат; 10 July 1927 – 22 June 2018) was a Russian mathematician.
Barenblatt graduated in 1950 from Moscow State University, Department of Mechanics and Mathematics. He received his Ph.D. in 1953 from Moscow State University under the supervision of A. N. Kolmogorov.
Barenblatt also received a D.Sc. from Moscow State University in 1957. He was an emeritus Professor in Residence at the Department of Mathematics of the University of California, Berkeley and Mathematician at Department of Mathematics, Lawrence Berkeley National Laboratory. He was G. I. Taylor Professor of Fluid Mechanics at the University of Cambridge from 1992 to 1994 and he was Emeritus G. I. Taylor Professor of Fluid Mechanics. His areas of research were:
Fracture mechanics
The theory of fluid and gas flows in porous media
The mechanics of a non-classical deformable solids
Turbulence
Self-similarities, nonlinear waves and intermediate asymptotics.
