Momentum Transfer for Flow over a Flat Plate with Blowing

Abstract

Note presenting a study of the effect on the boundary layer of blowing air through a porous flat plate into a main airstream flowing parallel to the plate. Measurements were made of velocity profiles and wall friction coefficients. The observed friction coefficients are predicted by mixture-length theory if the Reynolds number at the outer edge of the laminar sublayer is permitted to vary with the dimensionless ratio.
