ABSTRACT
KUETHE 24.08. 1905 Marshfield WI/USA 12.04. 2000 Ann Arbor MI/USA Arnold Martin Kuethe graduated in 1926 from the Ripon College, Ripon WI. He in 1933 obtained the PhD degree from Caltech, under the guidance of Theodor von Karman (1881-1963). Until 1938, he was then a research engineer of the Guggenheim Institute, Akron OH, then until 1940 lecturer at New York University. During the next two years, Kuethe then joined the National Advisory Committee of Aeronautics NACA. From 1941, he was a faculty member of the University of Michigan, Ann Arbor MI, and there from 1943 professor of aeronautical engineering. In parallel he was also a chief scientist in the Office of Air Research, Wright Field OH, and a consultant in aerodynamics. Kuethe was an Associate Editor of the Journal of Aeronautical Sciences, and a Fellow of the Institute of Aeronautical Sciences. Kuethe’s PhD thesis deals with the mixing of two parallel turbulent jets. Whereas Walter Tollmien (1900-1968) had considered two jets one of which is at rest, Kuethe investigated their mixing if both have a finite speed. Tollmien’s approach was thus generalized using Prandtl’s mixing concept. It was also observed, based both on a theoretical approach and detailed laboratory observations, that the velocity profiles beyond the potential jet core may be described with a unique function. Kuethe was thus able to adequately define the jet characteristics for an important case in practice, namely jet aviation. In the 1950s Kuethe considered the transition to turbulent flow in a tube, thereby generalizing Poiseuille flow in the laminar flow regime. Anonymous (1948). Arnold M. Kuethe.
