ACCURATE NAVIER-STOKES RESULTS FOR THE HYPERSONIC FLOW OVER A SPHERICAL NOSETIP

The unsteady, thin-layer Navier-Stokes equations for a perfect gas are solved with a linearized block, alternating direction implicit finite-difference solution procedure. Solution errors due to numerical dissipation added to the governing equations are evaluated. Errors in the numerical predictions on three-different grids are determined where Richardson extrapolation is used to estimate the exact solution. Accurate computational results are tabulated for the hypersonic laminar flow over a spherical body, which can be used as a benchmark test case. Predictions obtained from the code are in good agreement with inviscid numerical results and experimental data. © 1990 by the American Institute of Aeronautics and Astronautics, Inc.
