Orientational Effects in Heat-Conducting Smectic Liquid Crystals
The mutually competing orienting influences on heat-conducting smectic liquid crystals of temperature gradients, solid boundaries and shear flows are investigated. The case of Couette flow of smectic liquid crystals between concentric rotating cylinders is treated by solving the governing field equations based on the micropolar continuum theory of A. C. Eringen. Included in the solution of this problem is the derivation of explicit expressions for apparent viscosity coefficient, the orientation and micro-rotation fields, as well as heat-conduction. These expressions lead to a direct and more satisfying comparison with experimental results. The behavior of apparent viscosity under various shear-rates and temperatures as well as its dependence on the gap-width between the cylinders is investigated reaching good agreement with experimental results.
