Abstract
Solutions to the interacting laminar boundary-layer equations with surface injection are obtained for cases when classical theory predicts catastrophic blowoff. For the case of slot injection into a supersonic mainstream, implicit finite-difference solutions were obtained that show that interaction effects drastically alter the local pressure distribution and virtually eliminate the blowoff point. Favorable comparisons are made with asymptotic triple-deck solutions where appropriate. It is concluded that the present numerical technique works well, that the solutions honor triple-deck concepts, that blowoff does not occur in the injection region, and that separation will occur ahead of the slot, if at all.
