Numerical Computations for the Flow of Liquid Crystals

  • Bruce A. Finlayson


We report here calculations for average properties -viscosity, thermal conductivity, and dielectric constant — when a nematic liquid crystal is undergoing flow in three situations: Poiseuille flow in a capillary, and Couette and Poiseuille flow between flat plates including the presence of a magnetic field. By presenting the results in dimensionless form we are able to derive “universal” curves for these average properties in their dependence on the appropriate driving forces: pressure drop, surface velocity and magnetic field. The “universal” curves are nearly the same for p, p’-dimethoxy-azoxybenzene (PAA) and p’ methoxybenzylidene-p-n-butylaniline (MBBA) even though their respective viscosities differ markedly.
