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., Article, relation: isVersionOf: http://ci.nii.ac.jp/naid/110006148743/}, pages = {78--83}, title = {SPH法に関する基礎的研究 : 第1報,2相流境界問題の取扱い(流体工学,流体機械)}, volume = {72}, year = {2006} }
