Abstract
In this research, the accuracy and computational efficiency of gas-liquid two-phase fluid simulation were focused. For the estimation of the impulsive force acting on the upright wall, calculation precision was improved by applying a complete windward difference to the gas phase region and a difference scheme corresponding to the volume fraction of the fluid of each element in the gas-liquid mixture region. For computational efficiency, the computation time was reduced by eliminating the dependency between elements during forward substitution and backward substitution processing in the matrix solution and hybrid parallelizing it together with region segmentation method.
