CHARACTERIZATION OF CHAOTIC MOTION OF DNA IN LINEAR SHEAR FLOWS

摘要

Motion of macromolecules in flows is important to several disciplines such as DNA hybridization studies, self assembly of nanostructures, and transport of suspensions. The present study simulates the motion of macromolecular structures in linear shear flows. A molecular chain is modeled as a coarse-grained series of beads and springs. For a wide range of flow conditions, the flow appears chaotic, where quasi-stable limit cycles are observed for several smaller ranges of flow conditions.
