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 …

WebSubstituting the Lattice BGK Model for the Navier-Stokes Equation. Fluid flow analysis for aeronautical analysis often involves the creation of high-order mesh grids using algorithms such as Delauney triangulation. BGK models employ a simple lattice structure that can be constructed using a small portion of the processing time required for ... Web2 days ago · 1.Introduction. The boundary layer flows created by influencing boundaries are included in the study of classical fluid dynamics problems. Crane [1] studied Newtonian flow past a stretched plate in the ambient fluid standard in 1970. Partially velocity slip can happen along the stretching/shrinking boundary in particle fluids such as suspensions, …

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.
