Behavior of particles in turbulence: model-independent results

Most of the world around us (and inside us) is fluid, while a typical fluid flow is turbulence. Hence behavior of particles in turbulence is a very important practical problem. The problem is also challenging theoretically: particles' motion is driven by a force resulting from the action of a random, strongly non-linear velocity field whose statistics is essentially unknown. In this talk I will show how one can still say something on the behavior of particles in an unknown flow.
