Three-dimensional flow fields past reentry vehicles
Abstract
The development of an upwind relaxation scheme for obtaining steady state solution to the compressible Navier-Stokes equations in generalized coordinates is described. The method is second order accurate and naturally dissipative. It uses third order flux splitting of the convective and pressure terms and second order central differencing of shear and heat flux terms. A line Gauss-Sidel relaxation approach is used. The scheme is unconditionally stable as applied to a partial differential model equation. The algorithm is demonstrated for three dimensional flow past a reentry vehicle.
