Practical computation of axisymmetrical multifluid flows

Abstract

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 axisym-metrical gas generator. We describe successively how to deal with exact and global Riemann solvers, pressure oscillations, unstructured meshes, axisymme-try, boundary conditions and overly restrictive CFL conditions. The resulting algorithm is efficient and robust. 1.
