摘要

Numerical solution to the steady, supersonic, axisymmetric, turbulent, base flow for a tactical missile problem is computed with the Conservative Supra Characteristics Method (CSCM) Navier-Stokes flow solver on a system of overlapping, adaptive grids. Flow field details are resolved quite well initially with topologically appropriate overlapping grids. The solution is then further refined by grid adaptation to capture features of the flow. The predicted base pressure results achieved with the technique compares exceptionally well with experimental results. Proper choice of grid topology and adaptive regridding are found to be essential for accurate base flow predictions.
