Other AbstractA one-fluid numerical model for two-phase air-water flows is developed using finite volume scheme and free surface capturing method.Proper numerical dissipation introduced by advection scheme assures computational stability when dealing with the discontinuous density field and singularities in source terms.Furthermore,numerical dissipation implicitly represents the subgrid-scale effects instead of using an eddy-viscosity model in turbulence calculations.As exploratory research in this field,generation and evolution of wind-driven waves are simulated by proposed model and vortex structure in air side is studied based on the numerical results.Features of vortex structure,relations between vortex structure and Reynolds stress and characteristics of streamwise vortex transport are analyzed through comparison with channel flow.
