Validation of the New Version PNS3DT Code. G.U. Aero Report 9401.

In this Study, the PNS3DT code developed in the University of Glasgow to solve steady compressible parabolized Navier-Stokes equations with Baldwin-Lomax turbulence model is updated. The choice of primitive variables in the numerical scheme, different wall temperature conditions as well as the effect of different grid stretching strategies are tested in detail. Excellent agreement between the numerical and experimental results is observed. Thus, the code could provide a powerful tool to predict the aerodynamics characteristics on the ogive cylinder surface and to simulate the complicate flow structures around the cylinder
