In the types of flows associated with a body in flight, the boundary layer is very thin compared to the size of the body—much thinner than can be shown in a small sketch. With the figure in mind, consider Prandtl’s description of the boundary layer:3

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 … WebIn the lines of the recent paper [J. Amer. Math. Soc. 23(2) (2010), 591-609], we establish various ill-posedness results for the Prandtl equation. By considering perturbations of stationary non-monotonic shear flows, we show that for some C~∞ initial data, local in time H~1 solutions of the linearized Prandtl equation do not exist.
