Study on incompressible fluid analysis by three-dimensional particle method with finite volume techniques

Simulating violent free-surface flows by particle methods is effective. In recent years, the SPH (Smoothed Particle Hydrodynamics) method and MPS(Moving Simulation method) are considered representative especially in fields of ship engineering civil but these need various artificial parameters calculation may have unnatural large numerical oscillation calculated pressure values. order to avoid problems, authors proposed another based on finite volume techniques. The usefulness two-dimensional problems has been verified comparing fluctuation when a water tank model forcibly oscillated with corresponding experiment [1]. Therefore, this research, extended algorithm so that formula can be applied three-dimensional problems. effectiveness demonstrated applying dam break problem.
