Verification of a two-phase flow code based on an homogeneous model

Abstract : We present some verification test cases applied to a code developed at EDF R&D for the simulation of two-phase flows with mass transfer. The aim of this code is to allow the simulation of a wide range of industrial situations by considering all the thermodynamic disequilibria between the phases-pressure, temperature and chemical potential-and by assuming the kinematic equilibrium-a single velocity for both phases. The underlying homogeneous model [1, 13] is based on the Euler system of equations supplemented by a complex pressure law describing the behaviour of the mixture of the two phases. Different first-order schemes are compared on the basis of two analytical solutions: a classical Riemann problem and a steady-state heated pipe test.
