ON ENHANCEMENT OF ENERGY CONSERVATION PROPERTIES OF INCOMPRESSIBLE SPH METHOD FOR ACCURATE SIMULATION OF PROGRESSIVE WATER WAVES

Abstract

 The ISPH (Incompressible Smoothed Particle Hydrodynamics) method is a Lagrangian meshfree method, which is superior to simulate complicated violent flows with free surface including fragmentation and coalescence of water. Despite its advantages, however its energy conservation properties have not been examined rigorously. This paper aims at examining the effect of a few enhanced schemes for improving the energy conservation properties of a projection-based particle method, namely, the ISPH method by considering a set of wave simulations. It is shown that the most improved ISPH method, referred to as, CISPH-HS-HL-ECS-GC-DS with Wendland kernel, provides the best energy conservation property.
