Description

CFD modeling of multiphase systems is very challenging due to the wide range of length and time scales associated with each phase and their interactions. For disperse multiphase flows, CFD models can be formulated in terms of either a Eulerian or Lagrangian description of the disperse phase. However, both should provide the same information if formulated consistently.  In this presentation, I will focus on polydisperse two-phase flows with arbitrary material-density ratios (bubbly flow to granular flow), emphasize multi-scale CFD models in an Eulerian-Eulerian context, and discuss the state-of-the-art for treating pseudo-turbulence, and polydispersity while ensuring well-posed model equations.

Professor Fox joined Iowa State University as the Glenn Murphy Professor of Engineering in 1999, and was the Herbert L. Stiles Professor of Chemical Engineering from 2003-2012. Since 2001, he has been Associate Scientist at the US-DOE Ames Laboratory. He was promoted to Distinguished Professor in Engineering in 2010. Prior to joining ISU, Fox was an Associate Professor of Engineering at Kansas State University, and has held visiting professorships in Belgium, Denmark, France, Italy, Switzerland and The Netherlands. From 1987-88, he was a NATO Postdoctoral Fellow at LSGC in Nancy, France working in the area of chemical reaction engineering under the guidance of Prof. Jacques Villermaux. His numerous professional awards include a NSF Presidential Young Investigator Award in 1992 and the ISU Outstanding Achievement in Research Award in 2007.  Professor Fox was elected Fellow of the American Physical Society in 2007.  From 2012-14, he was a Marie-Curie Senior Fellow at the Ecole Centrale in Paris, France. In 2015 he was selected as an International Francqui Professor by the Francqui Foundation in Belgium, and awarded a Chaire d’Attractivité at the Université Fédérale Toulouse Midi-Pyrénées, France. In 2016 he was selected for the North American Mixing Forum Award for Excellence and Sustained Contributions to Mixing Science and Practice, and the Shell Particle Technology Forum Thomas Baron Award.


Professor Fox has made numerous ground-breaking contributions to the field of multiphase and reactive flow modeling.  The Fox group spearheaded many fundamental advances in the development of novel computational fluid dynamics (CFD) models to overcome specific scientific challenges faced in the chemical and petroleum industries.  He pioneered the use of in situ tabulation (ISAT) for efficiently handling complex chemistry in detailed multiphase reactor models, and developed powerful quadrature-based moment methods (DQMOM, CQMOM, EQMOM, CHyQMOM) for treating distribution functions (particle size, bubble size, etc.) required for CFD models of single and multiphase reactors.  The impact of Fox’s work extends far beyond chemical engineering and touches every technological area dealing with turbulent flow and chemical reactions (e.g., combustion, atmospheric science, nuclear fuel processing, etc.).  His first book, Computational Models for Turbulent Reacting Flows, published by Cambridge University Press (CUP) in 2003, offers an authoritative treatment of the field. His second CUP book in 2013, Computational Models for Polydisperse Particulate and Multiphase Systems, provides a comprehensive treatment of CFD model for disperse multiphase flows.
