Non-similarity Solutions of MHD Boundary Layer Flow

WebThe concept of the boundary layer is sketched in fig-ure 2. 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 The aerodynamic boundary layer was first hypothesized by Ludwig Prandtl in a paper presented on August 12, 1904 at the third International Congress of Mathematicians in Heidelberg, Germany. It simplifies the equations of fluid flow by dividing the flow field into two areas: one inside the boundary layer, dominated by viscosity and creating the majority of drag experienced by the bou… http://sites.apam.columbia.edu/courses/apph4200x/Prandtl_Boundary.pdf reachout dudley
