Structures and intermittency in a passive scalar model

Abstract

A one-dimensional white-in-time passive scalar model is introduced. Strong and persistent structures are shown to be present. A perturbative expansion for the scaling exponents is performed around a Gaussian limit of the model. The resulting predictions are compared with numerical simulations.
