Embedded Large-Eddy Simulation Using the Partially Averaged Navier–Stokes Model

Toward Large-eddy/reynolds-averaged Simulation of Supersonic Combustion

While flamelet-based progress variable models have matured to production-level in recent years for incompressible flows, little development toward compressible formulations of the flamelet model has ensued. For supersonic and hypersonic flows exhibiting combustion, an applicable flamelet-based combustion model must reflect the compressible nature of the flow, the tight coupling of the flow and ...

Large-eddy Simulation Using the Stretched-vortex Sgs Model

Large-eddy simulations of decaying turbulence and turbulent channel ow using the stretched-vortex subgrid-stress model are presented and discussed. In the stretched-vortex model, the subgrid turbulence is assumed to consist of vortices whose orientations are determined by the resolved velocity eld. This, combined with a relationship connecting the subgrid stresses to the vortex-structure orient...

Mixed Large-Eddy Simulation Model for Turbulent Flows across Tube Bundles Using Parallel Coupled Multiblock NS Solver

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...
