    • Assessment of LES techniques for mitigating the Grey Area in DDES models 

      Pont Vilchez, Arnau; Santos Serrano, Daniel; Trias Miquel, Francesc Xavier; Duben, Alexey; Revell, Alistair; Oliva Llena, Asensio (2019)
      Conference report
      Open Access
      The 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 ...

      The 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 ...
    • Noise radiated by an open cavity at low Mach number: Effect of the cavity oscillation mode 

      Martín Navarrete, Rocío; Soria Guerrero, Manel; Lehmkuhl, Oriol; Duben, Alexey; Gorobets, Andrey (2019-09-17)
      Article
      Open Access
      The present work focuses on the study of noise generation and radiation of an infinite open three-dimensional cavity at low Mach number with laminar upstream conditions that is of interest to understand noise generation ...
