Abstract:
A method to reduce drag on an airfoil is the so-called suction boundary layer. This helps stabilize the flow and prevent transition to turbulence. The flow over the infinite flat plate consists of a suction velocity through the porous wall, so that v = -V at the plate surface, y = 0. The flow in the stream wise direction is u(y) and at the plate satisfies the viscous no-slip condition but tends to the freestream value U far above the plate. We determine the velocity profile and the vorticity distribution for this flow, as well as the mechanisms that act to maintain this balance of the vorticity
