Sharp-interfaceモデルに基づく圧縮性気液二相流体解析に対し、保存則から導かれるVOF関数を用いた保存形の式及びその離散化手法を提案した。これらの概要と、一次元検証結果を報告する。

We proposed equations of conservative form using a VOF function from a conservation law and the discretization method of these equations for liquid-gas two-phase compressible fluid simulations based on a sharp-interface model. The outline of these proposals and results of one-dimensional numerical tests will be reported.
