Variational Multiscale Large Eddy Simulation of Turbulent Incompressible Flows

چکیده
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 use of staggered grid in the FD context, and the nonphysical oscillations the could appear in the convection dominated regime, when the mesh is not fine enough.

A Variational Multiscale Method for the Large Eddy Simulation of Compressible Turbulent Flows on Moving/Deforming Unstructured Grids
In this extended abstract a three level formulation of the variational multiscale (VMS) large eddy simulation (LES) method for turbulent flow computations on moving/deforming grids is presented. A consistent method to improve the VMS-LES method by computing the small-scale Smagorinsky constant (C′ s) dynamically as the flow develops (dynamic VMS-LES) is also developed. An application of VMS-LES...

In this study, turbulent flow around a tube bundle in non-orthogonal grid is simulated using the Large Eddy Simulation (LES) technique and parallelization of fully coupled Navier – Stokes (NS) equations. To model the small eddies, the Smagorinsky and a mixed model was used. This model represents the effect of dissipation and the grid-scale and subgrid-scale interactions. The fully coupled NS eq...
