On the Richardson Extrapolation of the Reynolds Stress with the Systematic Grid and Model Variation Method
A new operational Richardson extrapolation has been proposed to reconstruct the Reynolds stresses in LES. The method is based on three LES simulations as suggested in the Systematic Grid and Model Variation approach, and two new terms appear in the formalism. For a turbulent planar jet these two terms are small but reasonable and the extrapolation of the resolved shear stress works qualitatively well. The method is flexible and can be combined with different strategies. First results are promising, but more experience is needed with different flow configurations and higher Reynolds number.
