EnglishWiener's path integral theory is revisited, stressing that it holds only when the condition of local equilibrium is fulfilled. The diffusion of a particle in a two and three-dimensional shear flow is studied, showing that for small time intervals the particle diffuses freely, without being influenced by the velocity gradient of the incident flow, while for long time intervals it exhibits a time dependent dispersion coefficient.
