Abstract
A model of small scale anisotropy in turbulence is motivated by the proposal that intermittency properties in turbulence are governed by direct coupling between the largest scales and inertial range length scales. A one-parameter hierarchy of scalar derivative moment dependences on Reynolds number Re is predicted. Enforcing the observed constancy of the skewness, divergences of higher moments are predicted. The results support the proposed extremal nature of intermittency scalings.Keywords
