SOLUTION OF NON-SIMILAR 2D BOUNDARY LAYERS USING A TIME-MARCHING SCHEME

Abstract

A method is presented for the solution of 2D boundary layer equations by using a time-like algorithm in which the time-dependent boundary-layer equations are marched in time until the steady solution is found. The governing equations are numerically solved without employing the similarity law and transformed into a body-fitted curvilinear computational domain. Therefore, the computation is general and can be applied to flow over complex models. The method is applied to a number of experimental test cases, where excellent agreement between predictions and measurements is obtained.
