"Modeling and Simulation of Dynamics of Polymeric Solutions: Progress and Challenges "


[This is a CCNY/Columbia NSF-IGERT Soft Materials seminar]

ABSTRACT


Quantitative understanding of the influence of physico-chemical parameters on the dynamic evolution of microstructure in polymeric solutions plays a central role in processing of wide variety of micro-structured materials. Over the past decade tremendous progress has been made in the development of kinetic theory based coarse- grained micro-mechanical models for polymeric solutions as well as robust and highly accurate continuum and multi-scale simulation techniques for flow simulation of this class of fluids in complex kinematics flows. In this presentation, I will briefly review the progress made in these areas as well the remaining challenges in development of a unified approach for predicting dynamics of polymeric solutions in prototypical complex kinematics flows. Specifically, I will discuss:
  • The ability of the state-of-the art continuum level and multi-scale simulation techniques to accurately capture the experimentally observed flow kinematics, and polymeric stresses in a number of prototypical complex kinematics flow geometries,
  • A new high-fidelity and computationally efficient mesoscopic model for dynamics of dilute polymeric solutions as well as a unified approach for predicting dynamics of polymeric solutions in complex kinematics flows.

BRIEF ACADEMIC/EMPLOYMENT BACKGROUND:

Bamin Khomami graduated from the Ohio State University with a B.S. in Chemical Engineering and 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-St. Louis in 1987 as an Assistant Professor and was promoted to Associate Professor and Francis F. Ahmann Professor of Chemical Engineering in 1992 and 1997 respectively. In fall of 2006 he joined the University of Tennessee in Knoxville as the Armour T. Granger and Alvin ∓ Sally Beaman distinguished University Professor and Head of the Chemical and Biomolecular Engineering Department. In January of 2008, he also became the founding director of the Sustainable Energy Education and Research (SEERC) at University of Tennessee. In addition, between 1992 to 2006, he has served as visiting and adjunct Professor of Chemical and Mechanical Engineering at Stanford University, Universidad Nacional De Education A Distancia and the Technical University of Denmark. Through development of rigorous and novel multi-scale simulations strategies and detailed experimental studies, Khomami’s research group has been able to elucidate important physiochemical phenomena and predict system/process level features that have proven essential in successful design, development, and processing of a wide range of nano-and-micro structured materials. His current research interests are mainly focused on rational design and engineering of micro- and- nano-structured materials with applications to sustainable energy, biology, chemistry and medicine. To date, Khomami’s research has resulted in more than 110 refereed Journal publications and more than 80 invited presentations at universities in the US and abroad as well as national and international conferences including keynotes lectures at XIV International Congress of Rheology in 2004 and the European Conference on Reaction Engineering of Polyolefins in 2005 as well as a Plenary lecture at the 77th Annual meeting of the Society of Rheology in 2005. Khomami is a member of number of professional societies as well as a number steering and award committees. He also serves on the editorial board of Journals of Rheology, Applied Rheology and Non-Newtonian Fluid Mechanics. Khomami’s teaching interests are closely related to his research program. Specifically, in the past decade he has been involved in development and instruction of courses in rheology, transport properties of simple and complex fluids, polymer physics, biomolecular physics, sustainable technology development, processing science of microand- nano-structured materials, engineering of soft materials, applied mathematics as well as numerical analysis and multi-scale modeling and simulation.
