Fluid Simulation Based on Narrow Band FLIP Method

In order to improve the problems that a large number of particles does not contribute to the surface reconstruction 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 resampling 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.
