Title:Failure of kolmogorov refined similarity hypothesis in fluid turbulence
Author(s):Thoroddsen, Sigurdur T.
Subject(s):Kolmogorov's Refined Similarity Hypothesis
Fluid Turbulence
Abstract:Experiments in high Reynolds number turbulence demonstrate the failure of Kolmogorov's Refined Similarity Hypothesis (RSH). Previous experimental support for the hypothesis is shown to be distorted by the severe simplifications used in estimating the turbulence energy dissipation, which has invariably been based only on the streamwise gradient of the streamwise velocity component. However, when the dissipation is estimated by the streamwise gradient of a transverse velocity component the dependence between l∆ᶙI and (re*r)1/3 all but disappears. This dependence is required for the hypothesis to be valid.
