Assessment of LES techniques for mitigating the Grey Area in DDES models
(2019)
Text en actes de congrés
Accés obertThe slow RANS-LES transition is a well-known shortcoming in hybrid turbulence models such as DelayedDetached Eddy Simulation (DDES). The present work assesses the feasibility of 2D sensitive LES models for naturally ... -
Improving DES capabilities for predicting Kelvin-Helmholtz instabilities. Comparison with a backward-facing step DNS.
(2020-05-10)
Text en actes de congrés
Accés restringit per política de l'editorialThe Detached Eddy Simulation (DES) turbulence model presented by Spalart et al. (Comments on the Feasibility of LES for Wings, and on a Hybrid RANS/LES Approach, [1]) in the late 90s, was specifically designed to simulate ... -
