Thomas S. Lundgren
Thomas S. Lundgren (* around 1935 ) is an American engineer who specializes in turbulence and the dynamics of eddies.
Lundgren studied aeronautical engineering at the University of Minnesota with a bachelor's degree in 1954 and a master's degree in 1956, where he received his doctorate in hydrodynamics in 1960. He was then Assistant Professor, Associate Professor in 1963 and Professor of Aerospace Engineering and Mechanics in 1966. In 2000 he retired.
From 1972 to 1986 he was a consultant for Martin Marieta Energy Systems and he was also a consultant for Honeywell and Xerox.
In 1982 he was able to derive Kolmogorov's 5/3 law with a spiral-shaped vortex modeling (see Kolmogorow's microscale ). In 2002/3 he derived the Kolmogorow theory of homogeneous turbulence for the inertial range from the analysis of the Navier-Stokes equation with asymptotic developments (matched asymptotic expansions) (and corrections to it).
In 2006 he was awarded the American Physical Society's Hydrodynamics Prize and is a Fellow of the American Physical Society (1994).
