Abstract

Compressible linear viscous stability theory is used to study the effect of combined wall suction and cooling on the second mode instability in a flat plate boundary layer. While wall cooling destabilizes the boundary layer, calculations at Mach 4.5 and 8 show that wall suction may be used to stabilize the boundary layer with respect to second mode (subsonic) instability.
