Separation phenomenon in a hypersonic flow with strong wall cooling: Subcritical regime (Q687269)

This paper is concerned with a hypersonic flow past a cooled curved wall. The separation phenomenon at high Reynolds numbers is described using an interactive boundary-layer approach. For a problem of this type, a distinction must be made between two regimes subject to whether the global interaction between the boundary layer and the external flow is strong or weak. This depends on a hypersonic interaction parameter \(\chi\sim M_ e \text{Re }^{-1/2}\): if \(\chi\) is small, the interaction is weak; if it is large, the interaction is strong. The present study is applied to a flow with a weak global interaction regime when \(\chi\to 0\).
