Résumé

The computation of compressible two-phase flows with the Kapila five-equation model is studied. In the model (fast) acoustic waves and (slow) transport waves occur. In this paper a splitting-based Lagrange-projection-like numerical scheme for the Kapila five-equation model is introduced to decouple these physical phenomena. This approach is based on a Lagrange-projection method for the gas dynamics equations. The decoupling leads to two submodels which are alternately solved to approximate the solution of the full model. The acoustic submodel is cast into an almost conservative form and is solved using an HLLC-type Riemann solver. A classical upwind scheme is used for the transport part. The method allows for a general equation of state. Numerical computations are performed for two-phase shock tube problems, including a mixture problem. The results are in good agreement with reference results.
