Physical consistency of subgrid-scale models for large-eddy simulation of incompressible turbulent flows

Variational Multiscale Large Eddy Simulation of Turbulent Incompressible Flows

The variational multiscale (VMS) method was introduced in [4] as a framework for the development of stabilization techniques, which aim to overcome numerical difficulties encountered when using the standard Galerkin method, the finite element (FE) counterpart of centered finite differences (FD), namley, the compatibility condition between the velocity and pressure FE spaces, which require the u...

Large Eddy Simulation for Turbulent Flows

This thesis is concerned with one of the most promising approaches to the numerical simulation of turbulent flows, the Large Eddy Simulation (LES) in which the large scales of the flow are calculated directly, while the interactions with the small scales are modeled. Specifically, we analyze two new LES models, introduced in [30] and [51]. First, we sketch the derivation of the LES model introd...
