International audience; We are interested in free surface flows where density variations coming e.g. from temperature or salinity differences play a significant role in the hydrody-namic regime. In water, acoustic waves travel much faster than gravit

The Navier-Stokes system with temperature and salinity for free surface flows Part II: Numerical scheme and validation

Autor: Boittin, Léa, Bouchut, François, Bristeau, Marie-Odile, Mangeney, Anne, Sainte Marie, Jacques, Souillé, Fabien

In this paper, we propose a numerical scheme for the layer-averaged Euler with variable density and the Navier-Stokes-Fourier systems presented in part I (Boittin et al., 2018). These systems model hydrostatic free surface flows with density variatio

The present thesis deals with the modeling and numerical simulation of complex geophysical flows. Two processes are studied: sediment transport, and variable density flows. For both flows, the approach is the same. In each case, a reduced vertically-
