...Luca Sciacovelli; Aron Cannici; Donatella Passiatore; Paola Cinnella Purpose The purpose of the paper is to analyse the performances of closures and compressibility corrections classically used in turbulence models when applied to highly-compressible turbulent boundary layers (TBLs) over flat...

... al., 2006); and implicit large-eddy simulations (ILES). The Spalart–Allmaras turbulence model is used for both URANS and DDES. ILES does not require additional (turbulence) modeling (Grinstein et al., 2007), in that the numerical dissipation inherent to the WENO part...

... are evaluated and the efficiency of the turbulent models, K-ω shear-stress transport (SST), scale adaptive simulation (SAS) and delayed detached eddy simulation (DDES), in simulation of the nonlinear phenomena – i.e. the interaction between shock and boundary layer and the shock oscillations – is studied...

...Eric Goncalves; Dia Zeidan Purpose The aim of this work is to quantify the relative importance of the turbulence modelling for cavitating flows in thermal regime. A comparison of various transport-equation turbulence models and a study of the influence of the turbulent Prandtl number appearing...

... mounted at the back side of centrifugal rotor was undertaken. After detailed analysis of the influence of the used turbulence models on the results, a hybrid turbulent model Detached Eddies Simulation (DES) was chosen as the most suitable. Findings – Numerical control volume method with unsteady...
