A robust k−ε−/k elliptic blending turbulence model applied to near-wall, separated and buoyant flows

Assessment of RANS and DES methods for realistic automotive models

“…Hybrid RANS-LES models Spalart Allmaras (SA) [5] SST-DDES [6] Realizable k − ε (RKE) [7] SST-IDDES [8] k − ω SST (SST) [9] SA-DDES [6] Elliptic Blending k − ε v 2 − f (B-EVM) [10] SA-IDDES [11] Elliptic Blending Reynolds Stress Model (EB-RSM) [12] The principle behind hybrid RANS-LES methods is that a traditional wall-resolved LES is too expensive for complex high-Reynolds number flows that are influenced by near-wall effects. By applying a RANS model in the boundary layer and using LES outside of this region, the total cell count can by greatly reduced as RANS models do not require the same level of grid resolution in the boundary layer.…”

“…Several of these employed Reynolds-Averaged Navier-Stokes (RANS) models such as [10,6,4,29,12]. A review on this topic by F. Menter can be found in [25].…”

Application of recently developed elliptic blending based models to separated flows

“…The k À x SST and SSG models are compared to the blended k À e À v 2 =k (BL-v 2 =k) model of Billard and Laurence (2012) and the Elliptic Blending RSM (EBRSM) of Manceau and Hanjalić (2002). The first two of these are fairly widely used and well validated models, thus serving as a reference against which to judge the performance of the more recent BL-v 2 =k and EBRSM schemes.…”

“…the backward facing step flow of Parneix et al (1996)). Full details of the scheme can be found in Billard and Laurence (2012) and Billard (2011).…”

A Combined Experimental and Numerical Investigation of the Flow and Heat Transfer Inside a Turbine Vane Cooled by Jet Impingement

“…It is described in [14] and is seen in [4] as the most adapted model for impinging flows in the framework of 'classical' turbulence RANS closures. The k-ε Billard-Laurence model is described in [15]. This model was selected here as the most recent evolution of the former v 2 -f model.…”
