Separated flows and their representation by boundary-layer equations

Abstract : This report presents an efficient numerical method for computing laminar and turbulent boundary layers with and without separation. It represents a major extension to the earlier work described by the author and makes use of Keller's two-point finite-difference method to solve the governing equations. The nonlinear eigenvalue approach of the earlier work was found to be inappropriate to the separating boundary layers which are the main concern of this report and an alternative-approach, based on the solution procedures of Cebeci and Keller has been used. The solutions, which relate to attached and separating flows, were obtained with prescribed distributions of displacement thickness. (Author)
