Abstract
The Reynolds number dependence of the statistics of energy dissipation is i nvestigated in a shell model of fully developed turbulence. The results are in agreement with a model which accounts for fluctuations of the dissipati ve scale with the intensity of energy dissipation. It is shown that the ass umption of a fixed dissipative scale leads to a different scaling with Reyn olds which is not compatible with numerical results.
