Ludwig Prandtl
Ludwig Prandtl (* 4. February 1875 in freesing; † 15. August 1953 in Goettingen) was a German physicist. It supplied important contributions for the fundamental understanding of fluid mechanics and developed the boundary layer theory. On it the Prandtl number goes back
1894 began it in the technical university Munich its study, which it locked 6 years later with a doctor title. Subsequently, he worked as an engineer in engine works Augsburg Nuremberg on the development of manufacturing plants. With the work on a withdrawal system he came for the first time with the fluid engineering into contact.
He was a professor in Hanover and starting from 1. September 1904 in Goettingen. Due to the boundary layer theory developed by it it became 1904? also appointed the director/conductor of the aerodynamic laboratory Goettingen (AVA).
Together with max of Munk and Albert Betz, who became 1936 its successor with the aerodynamic laboratory Goettingen, he works on an effective formula for the investigation of the lift. Prandtl examined also the compressibility of air with high subsonic speed, also as Prandtl Glauert transformation admits.
Prandtl led 1946 from 1925 - as a director the institute for emperor William for investigation of flow. Its most famous work was the boundary layer theory, which it 1904 open-light.
- he investigated the supersonic flow and the shock waves developing thereby which were already predicted to 1860 by the Göttinger mathematician Bernhard Riemann theoretically for 1907.
- he built the first wind tunnel in Germany for 1908 and developed a wing theory, which affected the aircraft construction.
- 1909 he became director/conductor of the aerodynamic laboratory Goettingen (AVA).
- he investigated turbulent currents for 1910 and developed the Prandtl number.
- 1918 - 1919 it brought an important wing theory out, on the basis those it for the first time possible was, carrying specialized profiles on the basis theoretical studies to be developed.
Starting from 1920 he together with Adolf bus man works on a wind tunnel for supersonic flows.
- 1929 it developed a method for the computation of supersonic nozzles, like also today still e.g. in supersonic wind tunnels and rocket engines are usual.
