This paper deals with the parallel numerical simulation of cavitating o ws. The governing equations are the compressible, time dependent Euler equations for a homogeneous two-phase mixture. The equations of state for the density and internal energy are more complicated than for the ideal gas. These equations are solved by an explicit nite volume approach. After each time step uid properties, namely pressure and temperature, must be obtained iteratively for each cell. The iteration process takes much time, particularly if in the cell cavitation occurs. For this reason the algorithm has been parallelized by domain decomposition. In case where dieren t sizes of cavitated regions occur on the dieren t processes a huge load imbalance problem arises. In this paper a new dynamic load balancing algorithm is presented, which solves this problem ecien tly.
