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.8 pages, 1 figure, invited talk at 5th International Conf.
