Abstract

Here we study the dynamics and the conformational properties of Rouse polymers in random layered flows. We obtain explicit expressions for the 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 thermal 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.
