Smooth Particle Hydrodynamics for Surf Zone Waves

Abstract

Smoothed Particle Hydrodynamics (SPH) is a meshless numerical method that is being developed for the study of nearshore waves and Navy needs. The Lagrangian nature of SPH allows the modeling of wave breaking, splash-up, and the subsequent fluid turbulence, which in large part is comprised of coherent turbulent structures. The objectives of this project are to improve the SPH model for use in unraveling the physics of breaking waves, including the description of the wave-induced turbulence and sediment transport within the surf zone. The approach is based on improving various aspects of the SPH code; applying the code to more validation tests; and to examine in some detail new aspects of the model by applying it to different situations. The development of a hybrid model, that is, coupling the SPH particle model to a conventional finite difference model (a Boussinesq model, FUNWAVE) is being explored.
