Large eddy simulation of buoyant plumes [PDF]

, 2003
A 3d parallel CFD code is written to investigate the characteristics of and differences between Large Eddy Simulation (LES) models in the context of simulating a thermal buoyant plume. An efficient multigrid scheme is incorporated to solve the Poisson

Implicit Large Eddy Simulation of Environmental Urban Flows [PDF]

, 2010
Many environmental flows are turbulent flows. Depending on the physical aspects of the wind and the urban topology, turbulence might result into unfavourable or even dangerous conditions for the pedestrians.

Comparison of Subgrid-scale Viscosity Models and Selective Filtering Strategy for Large-eddy Simulations [PDF]

, 2013
Explicitly filtered large-eddy simulations (LES), combining high-accuracy schemes with the use of a selective filtering without adding an explicit subgrid-scales (SGS) model, are carried out for the Taylor-Green-vortex and the supersonic-boundary-layer ...

Localization of unresolved regions in the selective large-eddy simulation of hypersonic jets [PDF]

, 2010
A method for the localization of the regions where the turbulent fluctuations are unresolved is applied to the selective large-eddy simulation (LES) of a compressible turbulent jet of Mach number equal to 5.

Study on lattice Boltzmann method/large eddy simulation and its application at high Reynolds number flow

Advances in Mechanical Engineering, 2015
Lattice Boltzmann method combined with large eddy simulation is developed in the article to simulate fluid flow at high Reynolds numbers. A subgrid model is used as a large eddy simulation model in the numerical simulation for high Reynolds flow.
