Abstract : The Parabolized Navier-Stokes (PNS) equations are used to predict the viscous supersonic flow field over tangent-ogive-cylinder bodies with noncircular cross-section and finned body configurations. Current design interests make it desirable to gain some advanced knowledge of the aerodynamic characteristics of such bodies. Since the solution of the full, unsteady, Reynolds-averaged Navier-Stokes equations has its limitation due to computational resources, considerable interest exist in applying the PNS model to obtain a viscous supersonic flow field over realistic, complex configurations.
