A hybrid RANS/LES approach is presented and assessed considering several flows, which can be interpreted as the most general case of the NLDE approach as defined by Morris et al.

## Abstract In order to derive a possible path for developing a large eddy simulation (LES) applicable to high Reynoldsβnumber turbulent flows with heat transfer, a hybrid approach connecting LES with the Reynoldsβaveraged NavierβStokes (RANS) modeling in the nearβwall region is studied. In this st
The isothermal ow in an empty ventilated room is computed. Performances of linear and non-linear RANS, LES and a hybrid RANS/LES (LNS) models are compared. When compared to linear equivalents, the non-linear RANS models are found to modestly improve predicted velocities and Reynolds stresses. Genera
