Coarse-graining intramolecular hydrodynamic interaction in dilute solutions of flexible polymers

Ranganathan, Prabhakar; Sevick, Edith M; Williams, David


We present a scheme for coarse-graining hydrodynamic interactions in an isolated flexible homopolymer molecule in solution. In contrast to the conventional bead-spring model that employs spherical beads of fixed radii to represent the hydrodynamic characteristics of coarse-grained segments, we show that our procedure leads naturally to a discrete model of a polymer molecule as a chain of orientable and stretchable Gaussian blobs. This model accounts for both intrablob and interblob...[Show more]
