Accurate steam-water equation of state for two-phase flow LMNC model with phase transition

Abstract : This paper is dedicated to the design of incomplete equations of state for a two-phase flow with phase transition that are specific to the low Mach number regime thanks to the fact that the thermodynamic pressure can be considered constant. These equations of state supplement the 2D LMNC model introduced in previous works. This innovative strategy relies on tabulated values and is proven to satisfy crucial thermodynamic requirements such as positivity, monotonicity, continuity. In particular, saturation values are exact. This procedure is assessed by means of analytical steady solutions and comparisons with standard analytical equations of state which shows a great improvement in accuracy.
