Abstract

The study of intermittency in fluid turbulence is hampered by the lack of understanding of its basic mechanism [1]. The Kraichnan model of passive scalar advection by a rapidly varying velocity [2] is an example of a simplified model which displays intermittency, which is believed to be related to intermittency in turbulence. A mechanism for the generation of multiscaling in the Kraichnan model has been identified, and multiscaling exponents have been calculated by several methods [3, 4, 5, 6, 7].
