Abstract
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 presented.
