Keywords:Moving Particle Method, Moving Particle Semi-implicit Method, Jet, Tip of jet

A behavior of a heavy metal jet which ran into a water pool was analyzed with the Moving Particle Semi-implicit Method. A figure of the tip of jet was different from that of the experiment. We propose a modified calculating model with the MPS method.
