Effect of Wall Suction and Cooling on the Second Mode Instability
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.
