Two-fluid compressible simulations on GPU cluster

Two-fluid compressible simulations on GPU cluster

In this work we propose an efficient finite volume approximation of two-fluid flows. Our scheme is based on three ingredients. We first construct a conservative scheme that removes the pressure oscillations phenomenon at the interface. The construction relies on a rando...
