Description
We will discuss the issue of flow-orientation coupling in shear flows
of nematic liquid crystal polymers (LCP) using
the extended Doi theory with Marrucci-Greco potential (DMG) for long-range
molecular interaction. Firstly, we will present a few families of the
exact solutions of the DMG model in constant flow fields, which are
responsible for the phase transition and a variety of banded structures and
textures. Then, we will explore the orientational structures emerged in
simple flows of LCPs due to strong flow-orientation coupling and present
their scaling behavior with respect to physical parameters. Finally, we
will address the issue of stability for the steady state solutions.
