The aim of the first part of this work is to investigate if the value of the Kolmogorov constant, ±, predicted by LES is consistent with the assumed value of ± that was used to specify the Smagorinsky constant, C s, in the LES, and to determine the appropriate value of C s for decaying homogeneous turbulence at high Reynolds numbers. In the second part LES of axisymmetric decaying turbulence is used to calibrate the Rotta parameter, C 1, in the Rotta model for the slow pressure-strain rate.
