Vorticity-strain residual-based turbulence modeling of the Taylor-Green vortex

摘要

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.
