Modeling Water Waves with Smoothed Particle Hydrodynamics

Abstract

To improve the ability of the meshfree Lagrangian numerical method Smoothed Particle Hydrodynamics (SPH) to be a useful hydrodynamics model for breaking waves and the nearshore zone, particularly for case where spray and splash are important. To utilize the massively parallel graphics processing units on computers to develop the GPU-accelerated model GPUSPH to solve a number of problems relevant to the U.S. Navy. The science objective is to be able to accurately model the complex flows associated with breaking water waves, including instantaneous motions as well as (time-averaged) wave-induced flows, such as undertow, longshore currents, and rip currents.
