Rezumat:
The role of elastic stress in statistical and scaling properties of elastic turbulence in a polymer solution
flow between two disks is discussed. The analogy with a small-scale magnetodynamics and a passive
scalar turbulent advection in the Batchelor regime is used to explain the experimentally observed
statistical properties, the flow structure, and the scaling of elastic turbulence. The emergence of a new
length scale, namely, the boundary layer thickness, is observed and studied.
