A steam explosion is a physical event which can occur when two fluids are mixing and the temperature of one fluid is higher than the boiling point of the other. Steam explosions are an important area of study in nuclear engineering because the conditions for a steam explosion are fulfilled during some scenaria of severe nuclear reactor accidents, when the molten core comes into contact with the coolant water. Research is mainly focused on the steam-explosion premixing-phase since it determines the extent of the steam explosion. In order to discover how the steam-explosion premixing-phase simulation results are influenced by the accuracy of the numerical methods used for solving the multiphase-flow equations a simulation code named ESE (Evaluation of Steam Explosions) has been developed. With ESE a number of simulations of premixing-phase experiments, where different jets of cold or hot spheres are injected into a water pool, have been performed. Each experiment has been simulated with a first order accurate upwind method and the high-resolution method, which is second-order accurate. The simulation results and available experimental data have been compared.
