Abstract
The basic equations based on the integral method for solving compressible, laminar, boundary-layer flows are considered in some detail. The moment of momentum equation is added to the usual boundary-layer equations in order to form a complete set of equations. The governing equations for shock-wave or expansion-wave interactions with the boundary-layer are reformulated. The cold-wall similarity model of the interaction of a compressible, laminar, boundary-layer flow with a corner-expansion wave is investigated using certain approximations and initial conditions. The results compare well with other analytical models and with existing experimental data. (Author)
