The purpose of this project is to develop an understanding of the               rheology of a complex fluid via observation of its constituents'                microdynamics.  The optical measurements used provide noninvasive               probes of the motion of the fluid constituents.  Time-dependent                 rheooptical studies will be initiated with two general themes:  to              compare structures formed during flow as observed on small and large            length scales, and to extend the recently developed linear dichroism            and linear birefringence modulation methods.  The research will involve         red blood cells and liquid crystalline polymer aggregation under flow           conditions.  Studies of red blood cell aggregation may be of importance         in suggesting corrective measures for treating pathologic venous                hypertension.  Optical methods provide the most promising means of              investigating the little understood effects of polymer process                  conditions on fluid microstructure as well as the final polymer                 structural strength.
