Abstract
A computer program as been developed which numerically solves the steady incompressible Reynolds-averaged Navier-Stokes equations in two dimensions. The flow equations are solved in primitive variable form using the pseudo-compressibility approach with an upwind flux-difference split method for the convective terms. Turbulence is modeled using either the algebraic Baldwin-Lomax or the two-layer Chen-Patel turbulence model. The Chen-Patel turbulence model uses the two-equation k-E turbulence model in outer flow regions and the one-equation turbulence model of Wolfshtein in near-wall regions. Test cases are presented for flow about the NACA 0012 airfoil section at several angles of incidence, including flows with separation. Results are compared with published experimental data and with numerical results from the well-established ARC2D compressible Navier-Stokes flow solver.
