Did you know?
In physics and fluid mechanics, a Blasius boundary layer (named after Paul Richard Heinrich Blasius) describes the steady two-dimensional laminar boundary layer that forms on a semi-infinite plate which is held parallel to a constant unidirectional flow. Falkner and Skan later generalized Blasius' … See more Using scaling arguments, Ludwig Prandtl argued that about half of the terms in the Navier-Stokes equations are negligible in boundary layer flows (except in a small region near the leading edge of the plate). This leads to a … See more Suction is one of the common methods to postpone the boundary layer separation. Consider a uniform suction velocity at the wall $${\displaystyle v(0)=-V}$$. Bryan Thwaites showed … See more Since the boundary layer equations are Parabolic partial differential equation, the natural coordinates for the problem is parabolic coordinates.
