Webb28 nov. 2016 · To understand the interaction between wave-breaking induced turbulent coherent structures and suspended sediment transport, we report a Large-Eddy Simulation (LES) study of wave-breaking processes over a … Webbfor a dam-break, bore and wave breaking on a slope. It is found that the model can reproduce bubbly areas due to wave breaking reasonably well. Keywords: wave breaking; Large Eddy Simulation; bubbly flow; momentum conservation . INTRODUCTION . Wave breaking associated with rapid change of surface boundary …

Webbduring wave breaking. 2 MATHEMATICAL MODEL The large-eddy simulation (LES) approach is adopted in this study, for which the large-scale turbulence is resolved and a subgrid-scale model is employed to compute the unresolved scales of turbulence. The governing equations used for incompressible two-phase flow are based on Webbsubgrid-scale model is adopted for the large-eddy simulations of turbulent two-phase flows. The numerical method is validated using several examples, such as 2D solitary … WebbThe incoming waves are specified by a flux boundary condition. The waves are approaching in the shore-normal direction and are breaking on a plane, constant slope beach. The first few wave periods are simulated by a two-dimensional model in the vertical plane normal to the beach line. The model describes the steepening and the … thunder extreme athletics
