Viscosity coefficients of partially aligned nematic and nematic discotic liquid crystals
Phys. Rev. E 51(3), 1995, 2203 - 2212

The affine transformation model - formulated for ellipsoidal particles with axis ratio Q and previously used for the calculation of the viscous properties of nematic liquid crystals with perfect orientation order - is generalized to realistic uniaxial phases with imperfect order (Maier-Saupe order parameter S<1). For the nematic liquid crystals N-(4'-methoxybenzylidene)-4-(n-butyl) aniline (MBBA) and p-methoxy-p'-n-butylazoxybenzene (N4) and some cyanobiphenyls (kCB and kOCB with k=5,8) a comparison of the theoretically obtained Miesowicz viscosities with experimental data is made.
