Current Research

My research is directed at the application of fluid mechanics and rheology to industrial processes such as paper coating, paper web formation, printing, bubble coalescence, filtration, flotation, and polymeric film coating. Emphasis is placed on the development of simplified models to represent specific processes and the verification of these models with experiments. A number of novel experimental tools have been built to show the important mechanisms of various processes. Several unique areas have emerged in this effort understanding these processes.

  • Particle Motion Modeling
  • Suspensions are involved in many areas of coating and printing. The need to understand the rheological properties and the final properties of the coating layer has caused a new effort in modeling of particles motion in a flow field. The colloidal forces as well as the hydrodynamic forces are included in the model.

  • Coating Flows on Porous Webs
  • When suspensions and polymer solutions are contacted with a porous substrate, capillary and other external forces can cause the fluid phase to penetrate into the substrate. Unique methods have been developed to describe the coating flow field accounting for this penetration.

  • Thin Film Dynamics
  • Thin liquid films are important in a number of areas. Unique methods to describe the dewetting and rupture of thin films have been generated. Non-Newtonian rheology and hydrophobic attractive forces have been included in recent models.
