Abstract
Here we study the dynamics and the conformational properties of Rouse polymers in random layered flows. We obtain explicit expressions for t he mean squared displacement of the center of mass of the polymer as a function of time and number of beads. The averages involve both the t hermal noise and the realizations of the random flows. We find also an explicit dependence of the equilibrium value of the end-to-end vector on the number of beads and other dimensional parameters. Our results are compared to that for Rouse polymers immersed in non-random steady shear flows.
