摘要
The ever-widening applications of numerical calculations leads to a variety of new numerical methods, which are different in their solution algorithms as well as in the discretization of the governing equations. Despite this development, much work still remains in their improvement towards a fast, accurate and stable convergence. This work shows a numerical method for the solution of compressible and almost incompressible fluid flows using a finite volume, explicit Runge-Kutta multistage scheme, with central spatial discretization in combination with multigrid and preconditioning. Numerical tests are carried out for a vehicle launcher for Mach-number 3.75 and 2.0 using the Euler equations.
