Abstract
We present a numerical study of anisotropic statistical fluctuations in stationary homogeneous turbulent flows. By means of a new argument, we are able to predict the dimensional scaling exponents, ζ d l (p) = (p + l)/3, for the projections of the p-th order structure function in the l-th sector of the rotational group. Using these as a reference for normal behavioue, we show that the measured exponents are anomalous, i.e., they exhibit a clear deviation from the dimensional prediction. Some preliminary results about decaying anisotropic turbulence are also given.
