A molecular theory is presented for the dynamics of small-molecule nematic liquid crystals in shear flow. The flow-alignment angle is predicted to depend on the aspect ratio of the liquid crystal molecules, as well as the second and fourth moments, P2 and P4 of the distribution of molecules about the nematic director. This theory also predicts a transition from flow alignment to tumbling well away from any nematic-smectic-A phase transitions. © 1995 American Institute of Physics.

    By using a lattice Boltzmann scheme that solves the Beris-Edwards equations of motion describing liquid-crystal hydrodynamics, we study the response of cholesterics to shear and Poiseuille flows. The geometry we focus on is a flow along the direction of the helical axis, which is known to give...
