Flow alignment in a shearing nematic liquid crystal near a charged surface

The flow alignment angle θeff(y) and effective rotational viscosity coefficient γ₁ᵉᶠᶠ are investigated for polar liquid crystals (LCs), such as 4-n-octyloxy-4^'-cyanobiphenyl (8OCB), in the vicinity of a charged bounding surface. γ₁ᵉᶠᶠ and θeff(y) are calculated, for the stationary regime, in the framework of the conventional Ericksen - Leslie theory. Calculations of γ₁ᵉᶠᶠ, for the homeotropic alignment of 8OCB molecules, at a charged indium tin oxide--coated glass plate show an increase in γ₁ᵉᶠᶠ up to $7.8%.$
