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 L1, L2 are evaluated. We quantify statistical dependency by calculating the correlation function as well as a suitably defined Kullback information.
