Abstract

The steady state compressible Navier-Stokes equations are solved with an explicit Runge-Kutta scheme accelerated by multigrid and an implicit preconditioner. Extensions are made to include a k-ω/SST turbulence model and chemical reactions. The implicit smoother enables the use of high CFL numbers yielding fast convergence. We present applications to turbulent solutions for flows about wings and plumes and for flows with several chemical reactions.
