Abstract
We have solved the equations of transient shear flow for a model of a liqui d crystalline polymer that contains a long-range interaction term in the ne matic potential. The model exhibits a rich set of dynamics when the structu re and momentum equations are coupled, including a periodic vorticity 'burs t' near the shearing surface and very large gradients in velocity at discre te planes. Textures that are independent of the macroscopic scale were not observed. (C) 2000 Elsevier Science B.V. All rights reserved.
