This work presents the computational simulation results of turbulence phenomena in a high velocity multiphase flow, where the predominantly turbulent phase is the gaseous phase. For reliable simulation results the correct depiction of the flow in a single phase high velocity turbulent case is validated by comparing to other simulation and experimental results. This is a precondition for the simulation of the initial stages of the breakup of a droplet in a high Weber number flow. The role of the subgrid-scale turbulence is investigated for the mentioned class of fluid-dynamic flows. Simulation results are compared to experiments of droplet breakup at high Weber number.
