Flows of Liquid Crystalline Polymers

10:00 AM-12:00 PM
Room: Superior B

Liquid crystalline polymer (LCP) materials have been widely used in industrial and military applications. Modeling of the complex flows and characterization of the materials needs an effort across multiple disciplines ranging from model building to large-scale computation and analysis of complex dynamics. The participants in this minisymposium will present new molecular models for semi-flexible LCPs, a new continuum mechanical theory for nematic elastomers, kinetic theory for LCPs, analytical and numerical analysis on phase transitions in liquid crystal materials, modeling and computation of complex flows and formation of textures and defects in LCP flows. The study of LCP flows has come to the point where sophisticated computational and dynamical system tools are indispensable. The purpose of the minisymposium is therefore to enhance interactions among the active researchers.
