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

Abstract

The scientific and technical objectives of this research are: (1) develop a hybrid Eulerian and Lagrangian multi-fluids simulation capability, which combines the SPH and LSM with environmental input provided by coupled wind and wave simulations at far field; (2) use the numerical method developed in (1) to simulate wind-wave-ocean interactions at small scales to elucidate flow structure; (3) quantify and characterize wind-wave momentum and energy transfer and the injection to the upper ocean by breaking waves; and (4) simulate and identify key process in turbulence transport near steep and breaking waves.
