  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.
