| Abstract: | The stability of a supersonic boundary layer over an intensively cooled plate with respect to three-dimensional disturbances is investigated. Two neutral stability curves, the existence of which was established in 1], are contemplated. It is shown by asymptotic analysis that each of these two neutral stability curves separates into a closed and an ordinary neutral curve in a certain range of disturbance propagation angles. As the surface is cooled, the closed neutral curve contracts to a point. The results of asymptotic analysis were confirmed by numerical integration of the stability equations. |
