Thomas S. Lundgren

Thomas S. Lundgren (* 1935 ) is an American engineer who is particularly concerned with turbulence and dynamics of vortices.

Lundgren studied aeronautical engineering (Aeronautical Engineering) from the University of Minnesota with a bachelor 's degree in 1954 and a master's degree in 1956 and became a PhD in hydrodynamics 1960. He subsequently Assistant Professor, Associate Professor in 1963 and 1966, Professor of Aeronautical Engineering ( Aerospace Engineering and Mechanics ). In 2000 he retired.

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 with a spiral vortex modeling Kolmogorov 5/3 law can be derived ( see micro scale of Kolmogorov ). 2002/3, he led the Kolmogorov theory of homogeneous turbulence for the Inertialbereich from the analysis of the Navier -Stokes equation with asymptotic expansions (matched asymptotic expansions ) from ( and corrections thereto).

In 2006 he received the hydrodynamics Prize of the American Physical Society and he is a Fellow of the American Physical Society ( 1994).
