The full numerical simulation of quenching process requires tackling several phenomena: multiphase flows, fluid structure interaction and wetting, phase change, heat exchanges, etc. On the one hand, an adaptive Eulerian framework for the simulation of boiling phenomena that captures the most part is presented. However no solid-liquid contacts in parallel with boiling is allowed. On the other hand, a discontinuous Galerkin finite element method applied to the coupled unsteady Stokes/Cahn-Hilliard equations is presented. This framework provides simulations of wetting phenomena on simple cases. The opportunity to combine both frameworks for a full simulation of quenching process is discussed.
