In this presentation, Khomami will briefly review the progress made in fundamental understanding of non-equilibrium dynamics of polymeric melts as well as the remaining challenges in development of a unified approach for predicting dynamics of this class of fluids in processing flows. He will discuss: (1) The ability of the state-of-the theories to capture the dynamics of polymeric melts under flow, and (2) Our atomistic and mesoscopic simulations of flow of entangled polymeric fluids that for the first time elucidate the intricate connection between single chain dynamics and the macroscopic response of the fluid including the intriguing phenomenon of shear banding.
Khomami graduated from the Ohio State University with a B.S. in chemical engineering and a minor in mathematics in 1983 (summa cum laude) and obtained his M.S. and Ph.D. in chemical engineering at the University of Illinois-Urbana in 1985 and 1987, respectively. He joined Washington University in 1987 as an assistant professor and was named the Francis F. Ahmann Professor of Chemical Engineering in 1997. In 2006, he joined the University of Tennessee in Knoxville as the Granger and Beaman Distinguished University Professor and head of the Chemical and Biomolecular Engineering Department. In 2008, he was named the founding director of the Sustainable Energy Education and Research Center. He holds appointments in both chemical and biomolecular engineering as well as mechanical, aerospace and biomedical engineering at the University of Tennessee.
