Structure functions and energy dissipation dependence on Reynolds number

The dependence of the statistics of energy dissipation on the Reynolds
number is investigated in an experimental jet flow. In a range of about one
decade of $Re_{\lambda}$ (from about 200 to 2000) the adimensional mean
energy dissipation is found to be independent on $Re_{\lambda}$, while the
higher moments of dissipation show a power-law dependence. The scaling
exponents are found to be consistent with a simple prediction based on the
multifractal model for inertial range structure functions. This is an
experimental confirmation of the connection between inertial range
quantities and dissipation statistics predicted by the multifractal approach
