The use of LES subgrid‐scale models for shock capturing

International Journal for Numerical Methods in Fluids, 2002
AbstractA method for modelling of flow discontinuities based on deconvolution with a relaxation regularization (DDM) is compared with an essentially non‐oscillatory scheme (ENO) without further modelling and with a dynamic Smagorinsky subgrid‐scale model (DSM).

Subgrid scale modelling of transport processes

2010
Consideration of stabilisation techniques is essential in the development of physical models if they are to faithfully represent processes over a wide range of scales. Careful application of these techniques can significantly increase flexibility of models, allowing the computational meshes used to discretise the underlying partial differential ...

Subgrid Scale Modeling — An Introduction and Overview

1979
Subgrid scale modeling attempts to calculate details of the large scales while parameterizing the effects of small scales on these explicitly retained large scales statistically. Its origins go back to the meteorologists who, in their numerical integration of geophysical-scale flows, found it necessary to introduce an eddy viscosity, which provided an ...

Subgrid-scale modeling of compressible turbulent flows

Physics of Fluids A: Fluid Dynamics, 1991
A subgrid-scale (SGS) model for compressible turbulent flows is presented in the combination of the mass-weighted filtering procedure with the theoretical results from a two-scale DIA. This model consists of the filtered equations for mass, momentum, and internal energy as well as the equation for the intensity of SGS density fluctuation. In this model,

Subgrid Scale Models for Homogeneous Anisotropic Turbulence

1986
A statistical model is used to study the subgrid scale modelling problem for homogeneous turbulence. Pressure and transfer effects of the subgrid scales are modelled for wavenumbers small relative to the filter cut. The model is then extended to the complete wavenumber range from very large scales to the filter cut.
