A totally Eulerian finite volume solver for multi-material fluid flows

Abstract The purpose of this work is to present a new numerical scheme for multi-material fluid flows in dimension d ⩾ 1 . It is a totally Eulerian conservative scheme that allows to compute sharp interfaces between non-miscible fluids. The underlying flux scheme in single material cells is the so-called FVCF scheme, whereas interface reconstruction and directional splitting is used in multi-material cells. One of the novelty of our approach is the introduction of the concept of “condensate” which allows to handle mixed cells containing two or more materials. Moreover, it has been designed to allow free sliding of materials on each others, thanks to a material volume centered computation of variables in mixed cells.
