説明

An instruction of a coupled level set and volume of fluid(CLSVOF) method for computing incompressible two-phase flow is presented in this report. In the CLSVOF method, a level set method is combined with the volume of fluid method in order to calculate an interfacial unit normal vector and an interfacial curvature accurately as well as to achieve mass conservation. Procedures for interface reconstruction, advection algorithm and re-distance of a level set function are explained in detail. In addition, the CLSVOF method is applied to the film flow falling down along the vertical plate, as an example. The simulation results have shown to be in good agreement with the analytical solution derived from Nusselt's film theory.
