Prediction of the incompressible flow over a rearwardfacing step
Abstract
A viscous inviscid interaction scheme is presented for computing steady, two dimensional, incompressible, laminar, and turbulent flows over a rearwardfacing step. The boundary layer equations for the region of viscous flow and the Laplace equation for streamfunction in the region of inviscid flow are used. The boundary layer continuity and momentum equations are solved inversely in a coupled manner using an improved finitedifference calculation procedure. Consideration is given to the applicability of the boundary layer equations to two dimensional channel expansion flows with developed inlet velocity profiles. No inviscid flow region can be identified so that the viscous inviscid interaction procedure is not applicable. Predictions of laminar flows of this type using the inverse boundary layer numerical method are shown to be in agreement with existing NavierStokes solutions and experimental measurements.
