The combined effects of Brownian forcing and straining flow on the statistical description of particle dynamics are considered. Using a Fokker-Planck (pdf) model results are obtained for both instantaneous and continuous releases of particles into the flow. The approach shows that continuous sources generate true equilibrium distributions, and highlights important features of these distributions that have implications for the closure modelling of third-order velocity moments.
