摘　　要：探讨模拟射流雾化的若干典型VOF(Volume of Fluid)界面重构方法,并在开源流体力学计算软件OpenFOAM中运用VOF-LPT(Lagrangian Particle Tracking)耦合算法;该算法兼顾模拟的准确性和计算效率,可较为准确地模拟从连续液体到离散小液滴的射流雾化过程,并为更大尺度的模拟提供了一种可行的高效模拟方案。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.
