There are many mathematical models for describing compressible or incompressible flows with phase transition. In this contribution, we will focus on the Navier–Stokes–Korteweg model [12] (Appl Math Comput 272, part 2, 309–335, 2016) and a phase-field model: The compressible Navier–Stokes–Allen–Cahn model (NSAC) is able to model compressible two-phase flows including surface tension effects and phase transitions. In this contribution, we will present a discontinuous Galerkin scheme for the NSAC model. The scheme is designed to fulfill a discrete version of the free energy inequality, which is the second law of thermodynamics in the isothermal case. For situations near the thermodynamic equilibrium, this property suppresses so-called parasitic currents, which are unphysical velocity fields near the phase boundary.
