A Compressible Turbulent Flow Solver For Complex 3D Configurations

M.T. Manzari, K. Morgan


A numerical procedure is presented for simulating three dimensional turbulent
flow problems. The mass-averaged Navier-Stokes equations are solved together
with the low-Reynolds k - co two-equation turbulence model. The standard
Galerkin approach is used for spatial discretisation. Stabilisation and
discontinuity capturing is achieved by the addition of an appropriate diffusion.
An explicit multistage time stepping scheme is used to advance the solution in
time to steady state. The study of realistic problems involving complex
geometries can be achieved by using parallel computers. The results of a
simulation involving ' transonic turbulent flow about a complete aircraft are
