Abstract
Numerous models have been proposed in the literature to include phase change
into numerical simulations of two-phase flows. This review paper presents the modeling
options that have been taken in order to obtain a model for violent separated flows with
application to sloshing wave impacts. A relaxation model based on linear non-equilibrium
thermodynamics has been chosen to compute the rate of phase change. The integration in
the system of partial differential equations is done through a non-conservative advection
term. For each of these modelling choices, some alternative models from the literature
are presented and discussed. The theoretical framework for all phase change model (conservation equations and entropy growth) is also summarized.
