Abstract

The behavior of dilute polymers in an elongational flow has been an outstanding problem in polymer science for several decades [1-3]. In these flows, a velocity gradient along the direction of flow can stretch polymers far from equilibrium. Extended polymers exert a force back on the solvent leading to the important, non-Newtonian properties of dilute polymer solutions such as viscosity enhancement and turbulent drag reduction.
