Using singular values to build a subgrid-scale model for large eddy simulations

Franck Nicoud, +4 more
- 17 Aug 2011 - 
TL;DR: In this paper, an eddy-viscosity based, subgrid-scale model for large eddy simulations is derived from the analysis of the singular values of the resolved velocity gradient tensor.

Compressible large eddy simulation of turbulent combustion in complex geometry on unstructured meshes

Laurent Selle, +8 more
- 01 Jun 2004 - 
TL;DR: In this article, large-eddy simulations of an industrial gas turbine burner are carried out for both nonreacting and reacting flow using a compressible unstructured solver, and results demonstrate the capacity of the LES to predict the mean flow, with and without combustion, as well as its main unstable modes: it is shown, for example, that the PVC mode is very strong for the cold flow but disappears with combustion.

Large Eddy Simulations of gaseous flames in gas turbine combustion chambers

Laurent Gicquel, +2 more
- 01 Dec 2012 - 
TL;DR: In this article, two types of LES in complex geometry combustors and of specific interest for aeronautical gas turbine burners are reviewed: (1) laboratory-scale combustors, without compressor or turbine, in which advanced measurements are possible and (2) combustion chambers of existing engines operated in realistic operating conditions.

Turbulence statistics in fully developed channel flow at low reynolds number

John Kim, +2 more
- 01 Apr 1987 - 
TL;DR: In this article, a direct numerical simulation of a turbulent channel flow is performed, where the unsteady Navier-Stokes equations are solved numerically at a Reynolds number of 3300, based on the mean centerline velocity and channel half-width, with about 4 million grid points.

Numerical solution of the Euler equations by finite volume methods using Runge Kutta time stepping schemes

Antony Jameson, +2 more
TL;DR: In this paper, a new combination of a finite volume discretization in conjunction with carefully designed dissipative terms of third order, and a Runge Kutta time stepping scheme, is shown to yield an effective method for solving the Euler equations in arbitrary geometric domains.
