Three-Dimensional Boundary-Layer Flow Across A Wedge: A Numerical Investigation

Abstract

The present work investigates the flow of a continuous, laminar, 3-D boundary-layer over a fixed wedge, where the outside free-stream flows are approximately approximated by a power of distances. The controlling partial differential equations are transformed into coupled nonlinear ordinary differential equations with the necessary boundary conditions using surface similarity transformations. These equations involve two physical variables: pressure gradient and shear-to-strain rate. The resulting equations are numerically solved by the implicit finite-difference scheme known as the Keller-box approach. The obtained results are compared with those reported in the literature for a few special cases. Our numerical results indicate that the flow zone is divided into two areas: near-field (close to the wedge surface) and far-field field (mostly controlled by inviscid flow).
