Abstract

We develop numerical capabilities of direct numerical simulation and large-eddy simulation for turbulent flows with waving boundaries, which can be coupled with nonlinear surface wave simulation, to study the mechanism of turbulence-wave interaction. Simulation of turbulence in the vicinity of surface waves with various wave conditions reveals strong dependence of the statistics, structures, and dynamics of the turbulent flow on wave characteristics including wave phase, wave age, and wave nonlinearity. Simulation of nonlinear wave evolution provides wave growth quantification in a phase-resolving context, which is valuable for deterministic wavefield prediction. The results obtained in this study suggest the importance of two-way coupling between turbulence and waves in their dynamic evolution.
