Abstract
We present a lattice Boltzmann algorithm for the hydrodynamics of liquid cr ystals in the isotropic and nematic phases. The coupling between the tensor order parameter and the flow is treated consistently allowing investigatio n of a wide range of non-Newtonian flow behaviour. To illustrate the use of the method we present results for the effect of hydrodynamics on defect co alescence and demonstrate the occurrence of shear-banding and shear-thinnin g.
