An approximate non-asymptotic theory of weak normal shock-unseparated turbulent boundary layer interactions is given which includes the effect of surface mass transfer. The results of a parametric study of Reynolds number effects on various interaction properties without mass transfer, including skin friction, are first presented along with detailed comparisons with experiment including supercritical airfoil data. The extension and application of the theory to include moderate amounts of either suction or blowing through the surface is then discussed, especially as regards the influence of mass transfer on the skin friction behavior. As a consequence of its influence on the boundary layer profile shape away from the wall, small suction appreciably reduces the upstream influence and thickening effets of the interaction but hastens the onset of separation in the shock foot region.
