, 2005 When Ludwig Prandtl took up the Chair of Applied Mechanics at Göttingen University in 1904, the small university town became the cradle of modern fluid mechanics and aerodynamics. Not only did Prandtl found two research institutions of worldwide renown, the Aerodynamische Versuchsanstalt (AVA) and the Kaiser-Wilhelm-Institut für Strömungsforschung, but

Prandtl–Batchelor Flows on a Disk [PDF]
Communications in Mathematical Physics, 2022 For steady two-dimensional flows with a single eddy (i.e. nested closed streamlines), Prandtl (1905) and Batchelor (1956) proposed that in the limit of vanishing viscosity the vorticity is constant in an inner region separated from the boundary layer. In this paper, by constructing higher order approximate solutions of the Navier-Stokes equations and ...

Prandtl number and thermoacoustic refrigerators
The Journal of the Acoustical Society of America, 2002 From kinetic gas theory, it is known that the Prandtl number for hard-sphere monatomic gases is 2/3. Lower values can be realized using gas mixtures of heavy and light monatomic gases. Prandtl numbers varying between 0.2 and 0.67 are obtained by using gas mixtures of helium–argon, helium–krypton, and helium–xenon.

Local well-posedness of solutions to 2D magnetic Prandtl model in the Prandtl-Hartmann regime
Applications of MathematicsIn this paper, we prove local existence and uniqueness for the 2D Prandtl-Hartmann regine in weighted Sobolev spaces. Our proof is based on using uniform estimates of the regularized parabolic equation and maximal principle under the Oleinik's monotonicity assumption.

Prandtl and the Göttingen school [PDF]
, 2011 This is a historical review of "Prandtl and the Göttingen School" from his first work in 1898 to after WWII. We report the development of the boundary layer theory and the investigations that lead Ludwig Prandtl in the spring of 1945 to use a energy cascade model to derive for fully developed turbulence the Kolmogrov length scale. Working at the end of
