Two-Point Enstrophy Statistics of Fully Developed Turbulence
We study the two-point enstrophy statistics of three-dimensional stationary homogeneous isotropic turbulence in the framework of kinetic equations for the probability density functions. The unclosed terms are estimated from data obtained from direct numerical simulations. The results yield insights into the statistics of enstrophy production and dissipation as well as the interaction of different spatial scales.
