Karl Wieghardt (born November 20, 1913 in Vienna , † November 26, 1996 in Hamburg ) was a German physicist and fluid mechanic.

Live and act

Wieghardt was the son of the mathematics and mechanics professor Karl Wieghardt and grew up with his stepmother Auguste Lazar after his father's death . He studied mechanical engineering and technical physics at the TU Dresden (1932 to 1935) and in Göttingen , where he received his doctorate on a topic of aerodynamics under Ludwig Prandtl in 1938 (lift distribution on a rectangular wing). He then worked as his assistant at Prandtl's Kaiser Wilhelm Institute for Flow Research in Göttingen on his boundary layer theory. After the end of the war in 1945 he completed his habilitation in Göttingen and became a private lecturer there in October. Most of his work for the Navy and Air Force during World War II was not published but was kept secret. After the Second World War he worked on research assignments for the occupying powers at the Göttingen Institute (including writing the articles hydrofoil and heat transfer for the FIAT Reviews of German Science) and was at the Admiralty Research Laboratory of the British Navy in Teddington from 1949 to 1952 . From 1952 he was an assistant at the Institute for Shipbuilding at the University of Hamburg, where he became an associate professor for fluid mechanics in 1955 and a full professor in 1960. At the same time he gave lectures at the University of Hanover , where he was honorary professor from 1962.

Wieghardt worked like Prandtl both experimentally and theoretically z. B. over turbulent boundary layers, flow in granular media and ship hydrodynamics. He is the author of the well-known textbook “Theoretical Fluid Mechanics” (Teubner, 2nd edition 1974). With Klaus Oswatitsch he was also one of the editors of the “Guide through fluid mechanics” of his teacher Prandtl.

From 1967 to 1970 he was President of the Society for Applied Mathematics and Mechanics (GAMM). He was an honorary doctor from the University of Stuttgart .

He is the father of the chemist Karl Wieghardt .
