| Abstract: | An Unsplit Lagrangian Advection(ULA) scheme for Volume Of Fluid(VOF) method is presented in this article.The ULA scheme is developed based on an algorithm of Piecewise Linear Interface Construction(PLIC).The volume fluxes between cells are calculated through solving the new equation of the linear interfaces in cells in the ULA scheme.The fluxes flowing out from one cell is the inflow fluxes for another cell.In this way the whole fluid volume is conserved strictly without using any redistribution algorithms.... |
