Three-Dimensional Smoothed Particle Hydrodynamics Method for Simulating Free Surface Flows

摘要

In this paper, we applied an improved Smoothing Particle Hydrodynamics (SPH)method by using gradient kernel renormalization in three-dimensional cases. Thepurpose of gradient kernel renormalization is to improve the accuracy ofnumerical simulation by improving gradient kernel approximation. This method isimplemented for simulating free surface flows, in particular dam break casewith rigid ball structures and the propagation of waves towards a slope in arectangular tank.
