George G. Chase, Ph.D.

 

 

 

 

 

Professor of Chemical Engineering
Microscale Physiochemical Engineering Center
The University of Akron

Ph.D. (1989) Application of volume averaged continuum theory for multiphase systems.  The continuum theory provides the same organizational advantages as are available for single-phase systems.  Current research interests include fluid/solid separations and flows through porous media.  Specific applications include cake filtration, depth filtration, cross-flow filtration, electrorheological fluid flow through packed beds, and droplet coalescence in fibrous filters. Other areas of interest include nanofibers, high temperature fibers, fiber orientation in filter media, non-Newtonian flows in porous media, and catalytic reduction of NOx and CO gases.
