The elastic stress that a polymer exerts on a flow is strongly dependent on its orientation and is highly intermittent. Hydrodynamic interactions of individual polymers can enhance the fluctuations of individual molecules and result in a different non-equilibrium steady state. The transition to this new steady state can be related to the "Elastic Turbulence" phenomena observed in dilute polymer solutions. Host: Konstantin Turitsyn
