Modeling Water Waves with Smoothed Particle Hydrodynamics
Abstract
Summary/Abstract This proposal is to continue the development of the open-source numerical code GPUSPH to model the coastal zone, including realistic waves and wave-induced currents on arbitrary shorelines, with specific emphasis on short-crested waves and nearshore water temperature and dispersion. GPUSPH utilizes low-cost graphics cards to perform massively parallel computations and currently runs on a computer with a single graphics card or large multi-CPU/multi-GPU machines. The large machines provide the capability to model large regions (kilometer scale) and to have greater accuracy by providing more computational particles. Specific project objectives are to validate the nonlinear resonance between incident waves and edge waves (thus verifying the models ability to model nonlinear wave interactions), to add an energy equation to GPUSPH to keep track of water temperatures and the subsequent buoyancy effect for weakly stratified flows, and to implement an accurate multi-fluid version of GPUSPH for fluids with large differences in density, such as air/water, water/mud, and oil/water, and finally to complete the addition of surface tension into the model to accurately represent drops and bubbles.
