Wall-models for large eddy simulation based on a generic additive-filter formulation
(Georgia Institute of Technology, 2008-12-19)
In this work, the mathematical implications of merging two different turbulence modeling approaches are addressed by deriving the exact hybrid RANS/LES Navier-Stokes equations. These equations are derived by introducing ...
Study of compressible turbulent flows in supersonic environment by large-eddy simulation
(Georgia Institute of Technology, 2009-02-19)
A Large-Eddy Simulation (LES) methodology adapted to the resolution of high Reynolds number turbulent flows in supersonic conditions was proposed and developed. A novel numerical scheme was designed, that switches from a ...
Scaling of turbulence and turbulent mixing using Terascale numerical simulations
(Georgia Institute of Technology, 2007-08-09)
Fundamental aspects of turbulence and turbulent mixing are investigated using direct numerical simulations (DNS) of stationary isotropic turbulence, with Taylor-scale Reynolds numbers ranging from 8 to 650 and Schmidt ...
