ABSTRACT


The problem of simulating the motion of liquid crystalline polymers in flow is one of the most interesting and challenging problems involving the motions of complex fluids. The problem is also potentially important if it eventually provides a tool to produce better processing technologies that either avoid or minimize the breakdown of an initially aligned material into the well-known polydomain structure. In this work, we use a model derived from the work of Marrucci and Grecco to attack this problem. The focus is on predicting flow instabilities and the resultant formation of disclinations in a simple shear geometry. The present talk will attempt to provide an overview and progress report.
