DEVELOPMENT OF VOLUME CORRECTION METHOD FOR FREE SURFACE FLOW ANALYSIS USING DENSITY FUNCTION METHOD

Abstract

In this paper, a volume correction method for free surface flow analysis using density function method is proposed. The proposed volume correction method consists of two steps. The first step is to correct the volume of fluid phase. The second step is to correct the mass in the whole computational domain. The effect of the proposed method was checked by solving a dam break problem. Especially, volume conservations and mass conservations are checked. It is found that the proposed volume correction method is effective and this method makes an air-water interface sharp.
