Abstract
Linear stability behavior of self-similar streamwise corner flows is investigated under the influence of constant wall temperatures and suction rates perpendicular to each wall. For three Mach numbers, 0.1, 0.95, and 1.5, representing subsonic, transonic, and supersonic flow regimes, modes that propagate in the streamwise direction, i.e., with a wave number at the lateral boundaries, are studied first. Then, the influence of and on the stability of oblique modes with is investigated for the transonic flow. It is shown that the effect on the leading viscous mode with is the same for cooling and suction in the case of small variations in temperature and suction relative to the reference flow without control. However, the increase in stability of the inviscid corner modes depends on both the control method and the Mach number. The stability of oblique viscous modes increases as well and it is shown that at the critical point is independent of the wall temperature and the suction rate. In addition, a maximum spanwise wave number is observed for which the most critical viscous mode is still amplified.
