Abstract

Abstract

A new numerical model for three-dimensional flow is proposed, in which the Navier-Stokes (N-S) equations of incompressible fluid are solved as the governing equations for flow movement, and a fast particle level set method is adopted for free surface tracking. The N-S equations are solved only in the liquid phase for saving computational time. A ghost pressure method is utilized to close the Poisson equation on the free surface and the simple extrapolation of velocity is applied to obtaining the ghost velocity field out of the water domain. The flow model is verified by the modeled results of oscillatory flow, collapse of water column, impact of water drop and water infusion.
- free surface flow,
- fast particle level set,
