A fast method to solve incompressible boundary-layer interaction problems
A new and fast method to solve incompressible boundary-layer interaction problems will be presented. The method recognizes the important mutual influence of pressure and displacement thickness by simultaneously updating both these quantities as the boundary-layer is marched. The method can be overrelaxed and fast convergence is obtained, typically' within 10–15 iteration cycles.
The technique has been used with success for both a full boundary-layer formulation (large, but finite Reynolds number) and a triple-deck approach (limit Re→∞). Results obtained with these two formulations will be compared for a Carter/Wornom trough.
