Complex fluids. Our research interests lie in the field of fluid mechanics, especially as applied to the processing of polymer melts, polymer solutions, and colloidal dispersions. Among our research accomplishments are the development of boundary-layer theory for non-Newtonian fluids, measurements of wall slip in polymer melts, and elucidation of the dynamics of coagulation of colloids in flowing suspensions. More recently, engineers and scientists interested in the dynamic behavior of fluids composed of large molecules, deformable particles, or colloidal matter have found that the laws of conventional continuum fluid mechanics do not apply. Advances in computation and in our ability to measure forces and motions over small length scales have begun to reveal the laws of physics that do apply to complex materials. Our recent modeling efforts have demonstrated that systems in which particulates are initially randomly dispersed can evolve, under shear, into ordered materials, with important engineering consequences for strength, heat transfer, and electrical conductivity.
International engineering education. Work in this area stems from close ties with several educational institutions in France and in Asia. Particularly in Asia, the close liaison between universities and industry has provided the opportunity to participate in the development of strategies to stimulate technological development.
