from Wikipedia, the free encyclopedia

Hassan Aref (born September 20, 1950 in Alexandria , † September 9, 2011 in De Land , Illinois ) was an Egyptian-American engineer and physicist who worked on hydrodynamics . He was a professor at Virginia Tech .

Aref studied at the University of Copenhagen with the candidate's degree (Cand. Sci.) In physics and mathematics in 1975 (at the Niels Bohr Institute) and in 1980 at Cornell University in Eric Dean Siggia in physics doctorate (Turbulence and vortex dynamics in two dimensions ). In 1980 he became an assistant professor of engineering at Brown University and from 1984 to 1994 he was at Los Alamos National Laboratory . In 1985 he became an associate professor and later professor at the University of California, San Diego(both in the Applied Mechanics and Geophysics department). From 1989 to 1992 he was chief scientist at the San Diego Supercomputer Center. In 1992 he became professor and head of the department of theoretical and applied mechanics at the University of Illinois at Urbana-Champaign . From 2003 he was at Virginia Tech, where he headed the engineering faculty from 2003 to 2005. He died of an aortic dissection .

In 1986 he was visiting professor at the Technical University of Denmark in Lyngby and again in 2006 (Niels Bohr Visiting Professor). In 1986 he became an external member of the Danish Center for Applied Mathematics and Mechanics.

He dealt theoretically with hydrodynamics, especially vortex motion and its numerical simulation. He is considered to be the founder of the concept of chaotic advection , the formation of chaotic trajectories in otherwise laminar flows.

In 2011 he received the GI Taylor Medal , in 2000 he received the Otto Laporte Prize , in 1985 he received the Presidential Young Investigator Award and in 1988 he was Corrsin Lecturer. He was a Fellow of the American Physical Society (1988) and the American Academy of Mechanics (2000).

Before he became a US citizen in 1998, he was a Canadian citizen.

In 2000 he was President of the 20th International Congress of Theoretical and Applied Mechanics in Chicago and he was Chairman of the US National Committee on Theoretical and Applied Mechanics. With David G. Crighton he was the founding editor of Cambridge Texts in Applied Mathematics .

From 1984 to 1994 he was Associate Editor of the Journal of Fluid Mechanics.

He had been married to Susanne Eriksen since 1974 and had two sons.
