| Abstract | Abstract : We consider the use of multigrid methods to solve the Euler equations for hypersonic flow. We consider the steady state equations with a Runge-Kutta smoother based on the time accurate equations together with local time stepping and residual smoothing. We examine the effect of the Runge-Kutta coefficients on the convergence rate considering both damping characteristics and convection properties. We also show the importance of boundary conditions on the convergence rate for hypersonic flow. Also of importance of boundary conditions on the convergence rate for hypersonic flow. Also of importance are the switch between the second and fourth difference viscosity. Solutions are given for flow around a bump in a channel and flow around a biconic section. (Author) (kr) |
