| Summary: | 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 random sampling at the interface [5, 6]. Secondly, we replace the exact
Riemann solver by a faster relaxation Riemann solver with good stability properties
[4]. Finally, we apply Strang directional splitting and optimized memory
transpositions in order to achieve high performance on Graphics Processing Unit (GPU) or
GPU cluster computations. |
