The
Research Interests: 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.
