Abstract

Probability density function (PDF) of passive scalar dissipation (formula presented) is found analytically in the limit of large Peclet and Prandtl numbers (Batchelor-Kraichnan regime) in two dimensions. The tail of PDF at (formula presented) is shown to be stretched exponent (formula presented). At (formula presented).
