A dynamic subgrid‐scale eddy viscosity model
One major drawback of the eddy viscosity subgrid‐scale stress models used in large‐eddy simulations is their inability to represent correctly with a single universal constant different turbulentExpand

Wall-layer models for large-eddy simulations
The numerical simulation of high Reynolds number flows is hampered by model accuracy if the Reynolds-averaged Navier–Stokes (RANS) equations are used, and by computational cost if direct orExpand

Large-eddy simulation: achievements and challenges
Abstract In this paper, the present state of the large-eddy simulation (LES) technique is discussed. Modeling and numerical issues that are under study will be described, and results ofExpand

Large-eddy simulation of rotating channel flows using a localized dynamic model
Most applications of the dynamic subgrid‐scale stress model use volume‐ or planar‐averaging to avoid ill‐conditioning of the model coefficient, which may result in numerical instabilities.Expand

Numerical simulation of pulsating turbulent channel flow
Direct and large-eddy simulations of the Navier–Stokes equations are used to study the pulsating flow in a channel. The cases examined span a wide range of frequencies of the driving pressureExpand

The inner–outer layer interface in large-eddy simulations with wall-layer models
The interaction between the inner and outer layer in large-eddy simulations (LES) that use approximate near-wall treatments is studied.In hybrid Reynolds-averaged Navier–Stokes (RANS)/LES models aExpand

Two-layer approximate boundary conditions for large-eddy simulations
A new method to model the effect of the solid boundaries on the rest of the flowfield in large-eddy simulations is proposed. The filtered Navier-Stokes equations are solved up to the firstExpand

Subgrid-scale backscatter in turbulent and transitional flows
Most subgrid‐scale (SGS) models for large‐eddy simulations (LES) are absolutely dissipative (that is, they remove energy from the large scales at each point in the physical space). The actual SGSExpand

A priori and a posteriori tests of inflow conditions for large-eddy simulation
Comparisons of inflow conditions for large-eddy simulations of turbulent, wall-bounded flows are carried out. Consistent with previous investigations, it is found that the spectral content of theExpand
