Definition

A hybrid turbulence modeling approach that applies a Reynolds‑averaged turbulence model (RANS) in near‑wall attached boundary-layer regions and a large‑eddy simulation (LES) formulation in separated or free‑shear regions so that large, unsteady vortical scales are resolved away from walls while near‑wall small scales remain modeled; switching between RANS and LES behavior depends on local grid spa
