This thesis is devoted to the simulation of incompressible or low Mach turbulent flows, for nuclear safety applications. In particular, we focus on the development and...

The main objective of this thesis is to observe numerically and to analyze the effects of intermittency in a high Reynolds number turbulent channel flow. To this end,...

An immersed boundary method has been developed for the simulation of compressible flow and validated with reference test cases (pressure wave reflection and...

In this study, we present High-order Large Eddy Simulation (LES) of high Reynolds number turbulent ows over complex geometries. The Spectral Vanishing Viscosity...

The objective is to improve the stability and accuracy of finite volume spatial discretization on unstructured grids. The interest lies in the growing use of finite...

After more than 50 years of investigation, Large Eddy Simulation has demonstrated its benefit for unsteady flow simulation and is currently applied in a wide variety...

This work focuses on the development of the Discontinuous Galerkin (DG) method for the large-eddy simulation (LES) of turbulents flows. The DG method shows some...

Tidal bores are surge waves propagating upstream rivers as the tide rushes into estuaries. They induce large turbulences and mixing of the river and estuary flow of...

At solid rocket motor (SRM) start-up, an ignition overpressure (IOP), characterized by a strong positive peak and a large underpressure, is generated during the...
