Summary:The smoothed particle hydrodynamics (SPH) method developed by Lucy, Benz, Gingold, Monaghan and Liversky has a problem of numerical disorder at the boundary of 2 phase flow as gas and liquid. In this paper, new formulas of SPH method, named Relaxation equations, suited for treating 2 phase flow of non-viscous fluid are proposed. The Relaxation equations are constructed based on the mass conservation equation and the momentum conservation equation. By using the formulas, it is possible to suppress numerical disorder around the boundary of 2 fluids.
