Abstract:

A simple method of calculating the extent of the interaction of a corner expansion wave with a hypersonic boundary layer is presented. Arguments are presented to suggest that for small turning angles the principal feature of the flow is the interaction of the boundary layer and the expansion wave downstream of the corner. The net result is a large increase in the thickness of the boundary layer, and a greatly extended region of pressure decay. Numerical results based on the cold wall or local similarity approximation are given. Author
