Anomalous Transport Processes in Chemically Active Random Environment

By Juha Honkonen

Abstract

The effect of random velocity field on the kinetics of single-species and two-species annihilation reactions is analysed near two dimensions in the framework of the field-theoretic renormalisation group. Fluctuations of particle density are modeled within the approach of Doi. The random incompressible velocity field is generated by stochastically forced Navier-Stokes equation in which thermal fluctuations - relevant below two dimensions - are taken into account.Comment: 8 pages, 1 figure, invited talk at 5th International Conf.
