Three Dimensional Modeling of Breaking
Abstract
Smoothed Particle Hydrodynamics (SPH), a meshless Lagrangian numerical method, is used to examine the complicated three-dimensional flow field in breaking waves. SPH has an advantage over other computational methods to examine this problem as it allows for vorticity and splashing of the fluid. Here we are addressing the important issue of the source of vorticity in waves as they propagate and break in very shallow water, and we are discovering the mechanisms for breaking wave turbulence in the surf zone. More specifically, we are identifying the formation mechanisms for coherent turbulent structures observed in the field and laboratory, such as obliquely descending eddies, downbursting, and the hydrodynamics of the splash-up following a plunging breaker.
