A numerical model for aerated-water wave breaking

Abstract

This work presents a numerical model designed for the simulation of water-wave impacts on a structure when aeration of the liquid phase is considered. The model is based on a multifluid Navier-Stokes approach in which all fluids are assumed compressible. The numerical method is based on a finite volume algorithm in space and a second order Runge-Kutta method in time. A validation of this model is performed. It shows a good accuracy for acoustic and shock wave propagation in a bubbly liquid and for wave breaking.
