| Outline of Final Research Achievements |
An idea was newly propoesed for an advanced switching parameter used in a hybrid approach connecting large eddy simulation (LES) with Reynolds-averaged Navier-Stokes (RANS) modeling (the hybrid LES/RANS (HLR) model). In this study, a switching parameter was newly proposed by introducing knowledge of the near-wall turbulence properly. As a result, this parameter enabled the present HLR model to be smoothly replaced by a full LES if a grid resolution was fine enough in the near-wall region. This feature of the present model is notable because it has never been achieved in any previous LES/RANS hybrid model.
