Abstract: We evaluate several VOF(Volume of Fluid) methods for interfacial reconstruction. A VOF-LPT(Lagrangian Particle Tracking) coupling method is applied in OpenFOAM, an open source CFD package, to achieve both simulation accuracy and computational efficiency. This method simulates accurately from continuous liquid to discrete small droplets for jet atomization. It provides a feasible and efficient simulation scheme for simulation of jet atomization process on large scales.
