The premixing phase of a steam explosion covers the interaction of the melt jet with the water prior to any steam explosion occurring. To get a better insight into the hydrodynamic processes during the premixing phase, in addition to hot premixing experiments, where the water evaporation is significant, cold isothermal premixing experiments were also performed. The special feature of isothermal premixing experiments is that three phases are involved the water, the air and the spheres’ phase but only the spheres’ phase mixes with the other two phases, whereas the water and air phases do not mix and remain separated by a free surface. Our idea was to treat the isothermal premixing process with an original, combined multiphase model. In the developed combined multiphase model the water and air phases are treated with a free-surface model as a single, joint phase with discontinuous phase properties at the water-air interface. The spheres are treated, as is usual, with a multiphase flow model, where the spheres represent the dispersed phase and the joint water-air phase represents the continuous phase. The developed combined multiphase model was validated against the QUEOS isothermal premixing experiment Q08. A numerical analysis using different treatments of the water-air interface (level set, highresolution, upwind) was performed for the incompressible and compressible cases and the results were compared with experimental measurements.
