Abstract
A computer program has been developed which numerically solves the steady laminar incompressible Navier-Stokes equations in two-dimensions. The equations are solved in primitive-variable form using the pseudo-compressibility approach which converts the equations to a hyperbolic system. The convective terms are upwind differenced using a flux-difference split approach. A line-relaxation scheme is used to solve the numerical system of equations. Test cases are presented for flow about a circular cylinder and an airfoil section. Results are compared with numerical results from the well-establsihed ARC2D compressible Navier-Stokes code. Circular cylinder results are also compared with published experimental and numerical results.
