Inverse integral method for calculation of separated turbulent boundary layers

For the prediction of separated compressible turbulent two-dimensional boundary layers an inverse integral method was developed in which the surface pressure is defined as a dependent variable with either a prescribed displacement thickness or a prescribed streamline angle at the boundary layer edge. For the relations of the reverse flow velocity profiles similar solutions of Alber are used as a basis, and the history effects are considered by an empirical relation. The efficiency of the prediction method is appraised with tests in separated transonic flow.
