The 2007 Hybrid RANS-LES Symposium: An Outsider’s View

  • P. R. Spalart
Part of the Notes on Numerical Fluid Mechanics and Multidisciplinary Design book series (NNFM, volume 97)


The contributions, lessons, and trends found in the DESider Symposium Proceedings are discussed. Three broad classifications can be made among the papers:

  • The first is between studies which widen the code- and user-base of DES and its range of applications to establish the current level of quality, and those which bring out neighbouring hybrid concepts such as SAS for discussions and improvements.

  • The second is between ”natural” uses of DES with boundary layers fully covered by RANS, and uses with RANS only as a wall model in LES.

  • The third is between single-model methods such as DES, and zonal methods even if they are closely related.
