Abstract

The relaxation of the director field \( \hat n \), the velocity field v, the shear stress tensor component σ rz , and the temperature T has been investigated in the framework of the classical Ericksen-Leslie hydrodynamic theory of liquid crystals by numerically solving the system of nonlinear hydrodynamic equations, which describe the reorientation of the director field \( \hat n \) with due regard for the velocity field induced by a temperature gradient ▿T arising in a hybrid-oriented liquid-crystal capillary. The reorientation of the director field and the relaxation of the temperature field in the capillary have been studied for a number of hydrodynamic regimes that arise in hybrid-oriented capillary filled with the nematic liquid crystal 4-n′-pentyl-4′-cyanobiphenyl in response to the temperature gradient ▿T.
