Detached-Eddy Simulation Based on the v-f Model
Abstract: Detached-eddy simulation (DES) based on the v-f Reynolds-averaged Navier-Stokes (RANS) model is developed and tested. The v-f model incorporates the anisotropy of near-wall turbulence, which is absent in other RANS models commonly used in the DES community. The v-f RANS model is modi ed in order that the proposed v-f -based DES formulation reduces to a transport equation for the subgr...
متن کاملAssessment of Unstructured Grids for Detached- Eddy Simulation of High Reynolds Number Sepa- rated Flows
An assessment of unstructured grids for use in Detached-Eddy Simulation (and more generally in Large-Eddy Simulation) of massively separated ows is presented. The role of the grid, its generation and re nement, are considered via calculation of three high-Reynolds number turbulent ows of aerodynamic interest: the massively separated ow over a forebody in cross ow, the ow over a delta wing at 27...
متن کاملDetached-eddy Simulation: Current Status and Perspectives
Detached-Eddy Simulation (DES) is a hybrid technique proposed in 1997 as a numerically feasible and plausibly accurate approach for predicting massively separated flows. Since its inception the method has been applied to a range of configurations including simple shapes such as cylinders, spheres and aircraft forebodies, in addition to complex geometries including fighter aircraft. The accuracy...

15 صفحه اولEvaluation of Detached Eddy Simulation for Turbulent Wake Applications
Simulations of a low-speed square cylinder wake and a supersonic axisymmetric base wake are performed using the Detached Eddy Simulation (DES) model. A reduced-dissipation form of the Symmetric TVD scheme is employed to mitigate the effects of dissipative error in regions of smooth flow. The reduceddissipation scheme is demonstrated on a 2D square cylinder wake problem, showing a marked improve...
