Subgrid-scale modeling for Large-eddy simulations of compressible turbulence
نویسندگان
چکیده
We present two phenonmenological subgrid-scale (SGS) models for large-eddy simulations (LES) of compressible turbulent flows. A nonlinear model and a stretched-vortex model are tested in LES of compressible decaying isotropic turbulence. Results of LES at 32 resolution are compared to corresponding 256 direct numerical simulations (DNS). We use numerical schemes based on compact differences and study the effects of their order of accuracy on LES results. 47.27.Eq,47.27.Gs Typeset using REVTEX 1

Large-eddy simulation of turbulent flow over an array of wall-mounted cubes submerged in an emulated atmospheric boundary-layer
Turbulent flow over an array of wall-mounted cubic obstacles has been numerically investigated using large-eddy simulation. The simulations have been performed using high-performance computations with local cluster systems. The array of cubes are fully submerged in a simulated deep rough-wall atmospheric boundary-layer with high turbulence intensity characteristics of environmental turbulent fl...
متن کاملA-priori dynamic test for deterministic/stochastic modeling in large-eddy simulation of turbulent flow
The coherent/incoherent decomposition of the subgrid-scale stresses based on the wavelet de-noising procedure is exploited in the framework of large-eddy simulation of turbulence. Dynamic a-priori tests based on the perfect modeling approach are performed for decaying isotropic turbulence. The theoretical performances of deterministic/stochastic subgrid-scale models are evaluated during the sim...
متن کاملSubgrid-scale modeling of isotropic turbulence in compressible magnetohydrodynamic large eddy simulations
Despite the ever increasing availability of computational resources, fully resolved simulations of magnetohydrodynamic (MHD) turbulence are not going to be feasible for quite some time. For this reason, large eddy simulations (LES) have been introduced that only resolve large scales. In LES a low-pass filter is applied to the evolution equations, which introduces additional unknown terms. These...
متن کاملNumerical and modeling issues in LES of compressible turbulence on unstructured grids
This paper discusses numerical and modeling issues that arise in cell-centered finitevolume methods (FVM) for large eddy simulation (LES) of compressible flows on unstructured grids. These are: accuracy and stability of flux interpolation scheme, shock capturing strategy, and subgrid-scale (SGS) modeling. To enhance the accuracy of flux reconstruction, a new scheme with added first derivative t...
متن کاملConsistent subgrid scale modelling for lattice Boltzmann methods
The lattice Boltzmann method has become a widely used tool for the numerical simulation of fluid flows and in particular of turbulent flows. In this frame the inclusion of subgrid scale closures is of crucial importance and is not completely understood from the theoretical point of view. Here, we propose a consistent way of introducing subgrid closures in the BGK Boltzmann equation for large ed...
