Large Eddy Simulation of plunging breaking waves

Abstract : The scope of this work is to show the results obtained for simulating three-dimensional plunging breaking waves by solving the Navier-Stokes equations in air and water, coupled with a subgrid scale turbulence model (Large Eddy Simulation, LES). After a bibliographical study of the problem, the first part of the document is dedicated to the presentation and the validation of the numerical models and methods. In the next part, the numerical tool is used to treat two-dimensional configurations of solitary waves propagations. The last part of the document presents the application of the numerical methods for the complete decription of the breaking processes including overturning, splash-up and breaking induced vortex-like motion beneath the surface, by using 3D initial conditions corresponding to unstable periodic sinusoidal waves of large amplitudes in periodic domains.
