We study quantitative and qualitative aspects of the problem of turbulent transport of a passive scalar quantity in a random 2-d velocity field. In particular, we give precise meaning to some of the multifractal structure of the dissipation times, predicted earlier in the physics and engineering literatures. The unexplained terms of the abstract will be described more precisely in the talk.
This is based on joint work with Jingyu Huang.
