Flow alignment in a shearing nematic liquid crystal near a charged surface.
The flow alignment angle theta(eff)(y) and effective rotational viscosity coefficient gamma(eff)1 are investigated for polar liquid crystals (LCs), such as 4-n-octyloxy-4'-cyanobiphenyl (8OCB), in the vicinity of a charged bounding surface. gamma(eff)1 and theta(eff)(y) are calculated, for the stationary regime, in the framework of the conventional Ericksen-Leslie theory. Calculations of gamma(eff)1, for the homeotropic alignment of 8OCB molecules, at a charged indium tin oxide-coated glass plate show an increase in gamma(eff)1 up to 7.8%.
