Investigation of Incompressible Flow Past a Two Dimensional Wedge

Abstract

Incompressible flow past two dimensional wedges of various wedge apex angles has been investigated at different Reynolds numbers and angles of incidence both numerically and experimentally. A Navier-Stokes solver based on finite volume approach using a boundary fitted curvilinear structured O-grid has been developed to obtain details of unconfined flow past arbitrary two-dimensional body geometry. Standard k-ε turbulence model with standard wall functions has been incorporated to capture the flow field at high Reynolds numbers. Experiments have been performed on a 90 degree wedge at high Reynolds number to obtain the static pressure distribution on the wedge surface at different angles of incidence. Good agreement between the experimental and computed data has been achieved.
