(en) The discharge of a subcooled liquid or a liquid-vapor mixture at high temperature and pressure can occur in many industrial situations. This paper is focused on the analysis of critical flow models that are already available in the fast transient dynamics software EUROPLEXUS, or that are being implemented as new break boundary conditions. The results of the Moody, Fauske, Flinta, Henry-Fauske and DEM models are presented and compared with the Super Moby Dick experimental results. The best results are obtained for the DEM. Then preliminary results concerning the implementation of the DEM model as a break boundary condition in EUROPLEXUS are given.
