Reynolds-Averaged Navier Stokes (HANS) equations are solved using a third-order upwind biased Roe's scheme for the inviscid fluxes and second order central difference scheme for the viscous fluxes. The Baldwin & Lomax turbulence model is employed for the Reynolds stresses. The governing equations are solved using a finite-volume implicit scheme in body-fitted curvilinear coordinate system. Computations are reported for a flat plate apart from RAE 2822 and NACA 0012 airfoils. Results obtained for the flat plate at M=0.3, R-c = 4.0 x 10(6) compare favourably with the analytical solution. Computational results obtained for the two airfoils are compared with experiment. For both airfoils there is a good agreement. in surface-pressure distributions between computational results and experiments. However, resoanable agreement is obtained between computational and experimental skin-friction distributions for the RAE 2822 airfoil.
