(5)A Behavior of a Heavy Metal Jet with Free Surface Conditon of MPS Method
Keywords:Moving Particle Method, Moving Particle Semi-implicit Method, Jet, Cavity, Free Surface Condition
A behavior of a heavy metal jet which ran into a water pool was analyzed with the Moving Particle Semi-implicit Method. A pressure calculation without a free surface condition proved useful to suppress unrealistic cavity.
