This paper describes turbulence properties for a residual‐based turbulence model using fine‐scale approximations of strain and vorticity, emanating from a split of the non‐linear term in the Navier–Stokes equations. We will discuss the modelling of the fine‐scale terms and their impact in the light of simulation results of turbulent transition of the Taylor–Green vortex. Copyright © 2007 John Wiley & Sons, Ltd.
