为了改进 fluid implicit particle(FLIP)方法中大量粒子对界面重构没有作用的问题, 提出采用 narrow-band FLIP(NBFLIP)方法与体积分数方法进行多相流模拟的方法, 通过粒子重采样减少内部粒子数量, 以提升整体计算效率; 体积分数采用总变差不增的高精度数值格式进行追踪. 与相关文献实验对比表明, 文中方法可以实现丰富的单相流和多相流模拟效果.%In order to improve the problems that a large number of particles does not contribute to the surface re-construction in fluid implicit particle method (FLIP), a new method based on narrow-band FLIP and volume of fraction method is proposed. The method reduced the number of internal particles by means of particle resam-pling near the interface, and thus enhanced the overall computational efficiency; the volume fraction is tracked by the high accuracy numerical scheme with total variation diminishing in volume fraction model. The results show the new method proposed in the paper could achieve rich simulation effects of single phase and multiphase flow compared with the existing results.
