LAMINAR FLAT-PLATE BOUNDARY LAYER: EXACT-SOLUTION …
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' solution to wedge flow … 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 $${\displaystyle v(0)=-V}$$.
