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...

Parallel large-eddy simulations of turbulent flows with complex moving boundaries on fixed Cartesian grids

A parallel embedded boundary approach for large-eddy simulations of turbulent flows with complex geometries and dynamically moving boundaries on fixed orthogonal grids is presented. The underlying solver is based on a second-order fractional step method on a staggered grid. The boundary conditions on an arbitrary immersed interface are satisfied via second-order local reconstructions. The paral...

Applied large eddy simulation.

Large eddy simulation (LES) is now seen more and more as a viable alternative to current industrial practice, usually based on problem-specific Reynolds-averaged Navier-Stokes (RANS) methods. Access to detailed flow physics is attractive to industry, especially in an environment in which computer modelling is bound to play an ever increasing role. However, the improvement in accuracy and flow d...
