Hybrid Eulerian and Lagrangian Simulation of Steep and Breaking Waves and Surface Fluxes in High Winds

Abstract

This research aims at developing a hybrid numerical capability using a Lagrangian Smoothed Particle Hydrodynamics (SPH) method and an Eulerian Level-Set Method (LSM) for the simulation of steep and breaking waves in high winds. The ultimate goal is to establish an advanced computational framework for the investigation of wind-wave breaking in air-sea interaction processes, including the airflow separation over steep and breaking waves, the wind-wave momentum and energy transfer, the momentum and energy injection from breaking waves to the upper ocean, and the turbulence transport of scalars.
