抄録

In this paper we propose a “two-step simulation method” that can solve the dynamics of a sonic or supersonic jet flow and a liquid surface’s behavior simultaneously in a reasonable computing time. With this method, first, we calculate the sonic or supersonic jet flow from a nozzle, as a steady flow and without the water surface. After that, we calculate the liquid surface’s behavior as a two-phase flow, by using the results of the jet flow steady state calculation as boundary conditions. In this method, we can solve a complex flow problem which has multiple flows of different time scales. The simulation results show a good agreement with experimental results.
