abstract:
The logarithmic renormalization predicted by Kraichnan (1971) for the
direct cascade of enstrophy in the inertial range of two-dimensional
turbulence has been observed in a numerical simulation. A moderate
resolution allows for a very long time integration that provides very
good statistics. Deviations from Gaussianity in the vorticity probability
distribution are observed.
