Abstract

Two improvements have been done on VOF(Volume of Fluid) method. First, accuracy of surface tension calculation was improved by selecting surface locations of interface cells. The Second, we developed new method to estimate liquid volume fraction in interface cells that are different from each transport property in staggered mesh system. Comparison between arithmetic and harmonic means has been made both for dielectric constant and viscosity. The result by harmonic mean is closer to exact value than that by arithmetic mean.
