Journal ArticleDOI
A new version of detached-eddy simulation, resistant to ambiguous grid densities
Philippe R. Spalart,Sébastien Deck,Michael Shur,Kyle D. Squires,M. Kh. Strelets,Andrey Travin +5 more
TL;DR: In this paper, the authors proposed the DES97 model, denoted DES97 from here on, which can exhibit an incorrect behavior in thin boundary layers and shallow separation regions, when the grid spacing parallel to the wall becomes less than the boundary-layer thickness.
Journal ArticleDOI
A hybrid RANS-LES approach with delayed-DES and wall-modelled LES capabilities
TL;DR: In this article, a CFD strategy is proposed that combines delayed detached-eddy simulation (DDES) with an improved RANS-LES hybrid model aimed at wall modelling in LES (WMLES).
Journal ArticleDOI
Strategies for turbulence modelling and simulations
TL;DR: In this paper, the authors discuss the many levels possible for the numerical prediction of a turbulent flow, the target being a complete airplane, turbine, or car, and their hope is to stimulate reflection, discussion, and planning.
Journal ArticleDOI
Detached-Eddy Simulation
TL;DR: This review discusses compelling examples, noting the visual and quantitative success of DES and its principal weakness is its response to ambiguous grids, in which the wall-parallel grid spacing is of the order of the boundary-layer thickness.
Journal ArticleDOI
Wall-layer models for large-eddy simulations
Ugo Piomelli,Elias Balaras +1 more
TL;DR: In this article, the authors present three broad classes of approaches: bypassing this region altogether using wall functions, solving a separate set of equations in the nearwall region, weakly coupled to the outer flow, or simulating the near-wall region in a global, Reynolds-averaged, sense.
