Abstract

Experimental data of a fluid turbulence is analysed with respect to the statistical dependency of eddies of different length scales. The joint probability distributions of velocity fluctuations of two different length scales L 1, L 2 are evaluated. We quantify statistical dependency by calculating the correlation function as well as a suitably defined Kullback information.
