On the equilibria of the extended nematic polymers under elongational flow
MetadataShow full item record
We classify the equilibrium solutions of the Smoluchowski equation for dipolar ( extended) rigid nematic polymers under imposed elongational flow. The Smoluchowski equation couples the Maier-Saupe short-range interaction, dipole-dipole interaction, and an external elongational flow. We show that all stable equilibria of rigid, dipolar rod dispersions under imposed uniaxial elongational flow field are axisymmetric. This finding of axisymmetry significantly simplifies any procedure of obtaining experimentally observable equilibria.

Characterization of stable kinetic equilibria of rigid, dipolar rod ensembles for coupled dipole-dipole and Maier-Saupe potentials Zhou, Hong; Wang, H. Y.; Wang, Q.; Forest, M. G. (2007);We study equilibria of the Smoluchowski equation for rigid, dipolar rod ensembles where the intermolecular potential couples the dipole-dipole interaction and the Maier-Saupe interaction. We thereby extend previous analytical ...
