Simulation of dispersed two-phase flow using a coupled Volume-of-Fluid/Level-Set method

摘要

In this paper, a coupled Volume-of Fluid/Level-Set interface advection method is considered for the simulation of incompressible two-phase flow. With this method, mass conservation for both phases can be achieved up to specified tolerance in each computational cell. Representation of surface tension forces, however, is found unsatisfactory for the stationary droplet (Laplace) problem, as the procedure to couple the Volume-of-Fluid (VOF) and Level-Set (LS) functions gives rise to increased levels of spurious currents. An attempt to improve the coupling of VOF and LS interface descriptions is reported.
