Practical computation of axisymmetrical multifluid flows

Abstract:

We adapt the Saurel-Abgrall front capturing finite volumes method for an industrial simulation of compressible multifluid flows. We then apply the method to the case of air-water flow in the cooling chamber of an axisymmetrical gas generator. We describe successively how to deal with exact and global Riemann solvers, pressure oscillations, unstructured meshes, axisymmetry, boundary conditions and overly restrictive CFL conditions. The resulting algorithm is efficient and robust.
