Anomalous diffusion in fast cellular flows at intermediate time scales [PDF]

open access: yes, 2015
It is well known that on long time scales the behaviour of tracer particles diffusing in a cellular flow is effectively that of a Brownian motion. This paper studies the behaviour on "intermediate" time scales before diffusion sets in. Various heuristics
