Title: A New Boundary Treatment Method for Smoothed Particle Hydrodynamics
Abstract: Smoothed particle hydrodynamics method (SPH) has a good adaptability for the simulation of free surface flow problems. However, there are some shortcomings of SPH which are still in open discussion. This paper puts forward a new image boundary processing method and particle arrangement method and applies it to simulate the hydrostatic of complex geometry tank and solitary wave attacking problem. The results show that the new boundary processing method and particle arrangement algorithm for SPH can reduce the oscillations of pressure when simulating the problems with complex geometry boundary and the phenomenon of particle lacking nearby the boundaries is obviously decreased.
