A numerical procedure is presented for simulating three dimensional turbulen t flow pro blems. The mass-averaged Navier-Stokes equations are solved iogether with the low-Reynolds k - OJ two-equation turbulence model. The standard Galerkin approach is used for spatia l discretisation. Stabilisation and discont inuity capturing is achieved by the addition of an appropri ate diffusion. An explic it multistage time stepping scheme is used to advance the solution in time to steady state. The study of reali stic problems involving complex geometries can be achieved by using paral lel computers. The results of a simulation involv ing "transonic turbulent flow about a complete aircraft are presented
