The three-dimensional, compressible, viscous flow field around a general propeller geometry with the inflow at zero angles of incidence and yaw is computed using a Reynolds-Averaged Navier-Stokes equations solver. Results from validation test cases in which the laminar and turbulent incompressible flow over a flat plate are calculated demonstrate the flow solver is capable of accurately capturing boundary-layer behaviour. Euler solutions from flow field calculations around two very different propeller geometries show a high level of accuracy and efficiency. Preliminary results from a viscous flow field calculation around a two-bladed propeller are very encouraging.
