from Wikipedia, the free encyclopedia

Tony Maxworthy (born May 21, 1933 in Ealing, London , † March 8, 2013 ) was a British - American engineer who studied hydrodynamics . He was a professor at the University of Southern California (USC). Shortly before his death, he became a Distinguished University Professor there.

Maxworthy graduated from Imperial College , London with a bachelor's degree in 1954, from Princeton University with a master's degree in 1955, and received a doctorate in mechanical engineering from Harvard University in 1960 . Then he was group leader at the Jet Propulsion Laboratory (from 1968 as a consultant). From 1967 he was at USC, where he received a full professorship in 1970 and headed the Faculty of Mechanical Engineering from 1979 to 1989.

He dealt with a wide range of hydrodynamic problems, in particular with aerodynamic experiments, geophysical and environmental hydrodynamics (dynamics of the atmosphere on Earth and planets such as the atmosphere of Jupiter, tidal currents also in lakes and rivers, hydrodynamic problems with volcanic eruptions and avalanches, dust devils , Propagation of water with different salinity, wave dynamics, remote sensing), convection, turbulence, solidification and bio-hydrodynamics (e.g. flight of insects). He also dealt with magnetohydrodynamics, flow of liquid sodium, flame propagation and stabilization, capillary wave instabilities on jets and liquid layers, supersonic shock waves in wavy boundary layers and Hele Shaw cells . From 1975 he advised the BBC .

In 2011 he received the hydrodynamics prize of the American Physical Society , in 1990 the Otto Laporte Prize and in 2003 the GI Taylor Medal . He was a Fellow of the National Academy of Engineering , the American Physical Society , the American Academy of Arts and Sciences, and the American Geophysical Union . In 1980/81 he received the Humboldt Research Prize and was thus at the Institute for Hydromechanics at the University of Karlsruhe and at the Chair for Fluid Mechanics at the Friedrich-Alexander University Erlangen-Nuremberg and in 1990 he was Senior Scientist at the Norwegian National Science Organization. He traveled extensively, was a lifetime Fellow of Clare Hall in Cambridge, worked with the DAMTP in Cambridge (Herbert Huppert), the University of Grenoble (LEGI, Laboratory of Geophysical and Industrial Fluid Flows, Emil Hopfinger) and the University of Western Australia (Jorge Imberger).

Maxworthy holds a patent for a delta wing with buoyancy aid (1991).
