Stabilization mechanisms are investigated using numerical simulation and linear analysis. Wave packet evolution is considered for expansion corner flows in the two cases: first-mode instability (Mach number 3, adiabatic wall), and second-mode instability (Mach number 6, cooled wall). Stability properties and spectral characteristics of the disturbance fields are analyzed.
