Résumé

We introduce here some possible way to deal with the unsteady interfacial coupling of two distinct two-phase flow codes. The left code relies on the standard two-fluid approach, and the right code provides approximations of solutions of the Homogeneous Relaxation Model (HRM). The basic idea of the coupling method is to introduce a father model, which corresponds to the two-fluid two-pressure approach, and to define convective fluxes through the interface, once a prolongation of initial conditions on both sides of the coupling interface has been performed. A sketch of the algorithm is provided. More details are given in the paper [HER 06]. A few numerical results show a rather good behaviour of the coupling approach.
