Abstract
In order to examine the difference between shear-induced and extensional-induced associating
polymer assemblies at the molecular level, Brownian dynamics simulations with the bead-spring
model were carried out for model DNA molecules with sticky spots. The radial distribution of
molecules overestimates from that in the absence of flow and increases with increasingWeissenberg
number in extensional flow, but slightly underestimates without regard to shear rate in shear flow.
The fractional extension progresses more rapidly in extensional flow than in shear flow and the
distribution of fractional extension at the formation time has a relatively sharper peak and narrower
spectrum in extensional flow than in shear flow. In shear flow, the inducement of the assembly
mainly results from the progress of the probability distribution of fractional extension. However, in
extensional flow, the assembly is induced by both the progress of the probability distribution and
increasing the val
