Abstract

We consider advection of a passive scalar θ(t, r) by an incompressible large-scale turbulent flow. In the framework of the Kraichnan model all PDF's (probability distribution functions) for the single-point statistics of θ and for the passive scalar difference θ(r₂) - θ(r₂) (for separations r₁ - r₂ lying in the convective interval) are found.
