NUMERICAL-SIMULATION OF A WAVE CHANNEL

The application of the Mixed Eulerian-Lagrangian method to the simulation of transient free surface flows in the vicinity of a free surface piercing structure is considered. Particular attention is given to the validation of the numerical procedure. Several applications are studied. Comparisons between the results of the numerical scheme and those of approximate theories or experiments are shown. They demonstrate the accuracy and versatility of the simulation that can be used as a "standard" to check the applicability of approximate theories. The main limitation of the method is that it cannot account for viscous effects, in particular in the vicinity of the free surface. Approximate ways to simulate dissipative phenomena associated to breaking would be most useful.
