Prandtl number — The Prandtl number mathrm{Pr} is a dimensionless number approximating the ratio of momentum diffusivity (kinematic viscosity) and thermal diffusivity. It is named after the German physicist Ludwig Prandtl.It is defined as::mathrm{Pr} = frac{… … Wikipedia
Prandtl, Ludwig — born Feb. 4, 1875, Freising, Ger. died Aug. 15, 1953, Göttingen, W.Ger. German physicist, considered the father of aerodynamics. He taught at the University of Göttingen (1904–53). His 1904 discovery of the boundary layer at the surface of a body … Universalium
Prandtl-Meyer expansion fan — A Prandtl Meyer expansion fan is a centered expansion process, which turns a supersonic flow around a convex corner. The fan consists of infinite number of Mach waves, diverging from a sharp corner. In case of a smooth corner, these waves can be… … Wikipedia

Turbulent Prandtl number — The turbulent Prandtl number (Pr t) is a non dimensional term defined as the ratio between the momentum eddy diffusivity and the heat transfer eddy diffusivity. It is useful for solving the heat transfer problem of turbulent boundary layer flows … Wikipedia
Tesla turbine — The Tesla turbine is a bladeless centrifugal flow turbine expander patented by Nikola Tesla in 1913. It is referred to as a bladeless turbine because it uses the boundary layer effect and not a fluid impinging upon the blades as in a conventional … Wikipedia
