Mass transfer modelling for compressible two-phase flows
Résumé
Two diffuse interface models for compressible two-phase flows including phase transfer are presented. The first one is
based on conservation laws for mixture variables with an additional equation for the void ratio in which the mass transfer appears
explicitly in the source term. The second one is fully conservative and a relaxation model is built to introduce the mass transfer
between phases. The stiffened-gas equation of state is used for calculating thermodynamic properties. Simulation results from
expansion tube cases with cavitation are presented.
