Abstract: Quantitative understanding of the influence of environmental variables
on the dynamic evolution of microstructure in polymeric fluids plays a central role in soft matter physics as well as the processing of a wide variety of micro-structured materials. To this end, accurate models and robust and efficient simulation techniques
that can quantitatively predict the flow-micro structure coupling in complex fluids are essential in knowledge-based design and manufacture of polymer-based products, which constitute a significant portion (>15%) of manufacturing economy of united states today.
This segment of the economy is forecasted to nearly double in the next decade due to the significant national investment in additive manufacturing.
In this presentation, I 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. Specifically, I 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 mesocopic 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.
Bio: Bamin 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 fall of 2006 he joined the University of Tennessee in Knoxville as the Granger & 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. Currently he holds appointments in both Chemical and Biomolecular Engineering as well as Mechanical, Aerospace
and Biomedical Engineering at the University of Tennessee.
In addition, between 1992 to 2006, he served as a visiting Professor of Chemical Engineering at Stanford University, Universidad
Nacional De Education A Distancia, and the Technical University of Denmark.
In 2015, he co-founded Celtig LLC to produce high-quality graphene nanoplatelets or flakes (marketed under the trade name
Cicarbo™) and to distribute commercial quantities of this line of products to markets worldwide.
