Derive prandtl’s boundary layer equations

WebDec 8, 2016 · We provide a systematic derivation of boundary layer models in magnetohydrodynamics (MHD), through an asymptotic analysis of the incompressible MHD system. We recover classical linear models, related to the famous Hartmann and Shercliff layers, as well as nonlinear ones, that we call magnetic Prandtl models. We perform … WebThis equation is named after the German fluid dynamics physicist Paul Richard Heinrich Blasius (1883--1970), a student of Ludwig Prandtl (1875--1953), who provided a mathematical basis for boundary-layer drag. In 1908, Blasius solved the equation by using a series expansions method. In 1912, Toepfer solved the Blasius equation numerically …
