A New Version of Detached-eddy Simulation, Resistant to Ambiguous Grid Densities

- P. Spalart, S. Deck, M. Shur, K. Squires, M. Strelets, A. Travin
- Physics
- 30 May 2006

Detached-eddy simulation (DES) is well understood in thin boundary layers, with the turbulence model in its Reynolds-averaged Navier–Stokes (RANS) mode and flattened grid cells, and in regions of… Expand

Generation of Turbulent Inflow Data for Spatially-Developing Boundary Layer Simulations

- T. Lund, Xiaohua Wu, K. Squires
- Geology
- 1 March 1998

A method for generating three-dimensional, time-dependent turbulent inflow data for simulations of complex spatially developing boundary layers is described. The approach is to extract instantaneous… Expand

A dynamic subgrid‐scale model for compressible turbulence and scalar transport

- P. Moin, K. Squires, W. Cabot, Sangsan Lee
- Physics
- 1 November 1991

The dynamic subgrid‐scale (SGS) model of Germano et al. [Phys. Fluids A 3, 1760 (1991)] is generalized for the large eddy simulation (LES) of compressible flows and transport of a scalar. The model… Expand

Partitioning of particle velocities in gas-solid turbulent flows into a continuous field and a spatially uncorrelated random distribution : theoretical formalism and numerical study

- P. Février, O. Simonin, K. Squires
- Physics
- 25 June 2005

The velocity distribution of dilute suspensions of heavy particles in gas–solid turbulent flows is investigated. A statistical approach – the mesoscopic Eulerian formalism (MEF) – is developed in… Expand

Direct numerical simulation of turbulence modulation by particles in isotropic turbulence

- M. Boivin, O. Simonin, K. Squires
- Physics
- 25 November 1998

The modulation of isotropic turbulence by particles has been investigated
using direct numerical simulation (DNS). The particular focus of the present work is
on the class of dilute flows in which… Expand

Particle response and turbulence modification in isotropic turbulence

- K. Squires, J. Eaton
- Physics
- 1 July 1990

The effect of turbulence on particle concentration fields and the modification of turbulence by particles has been investigated using direct numerical simulations of isotropic turbulence. The… Expand

An approach to wall modeling in large-eddy simulations

- N. Nikitin, F. Nicoud, B. Wasistho, K. Squires, P. Spalart
- Physics
- 8 June 2000

Channel flow with friction Reynolds number Reτ as high as 80 000 is treated by large-eddy simulation at a moderate cost, using the subgrid-scale model designed for detached-eddy simulations. It… Expand

Numerical investigations of flow over a sphere in the subcritical and supercritical regimes

- G. Constantinescu, K. Squires
- Physics
- 5 April 2004

The flow field around a sphere in an uniform flow has been analyzed numerically for conditions corresponding to the subcritical (laminar separation) and supercritical (turbulent separation) regimes… Expand

Preferential concentration of particles by turbulence

- K. Squires, J. Eaton
- Physics
- 1 May 1991

Direct numerical simulation of isotropic turbulence was used to investigate the effect of turbulence on the concentration fields of heavy particles. The hydrodynamic field was computed using 643… Expand

The inner–outer layer interface in large-eddy simulations with wall-layer models
