Research Interests

My research falls into two main categories:

  • Non-Newtonian fluid mechanics: Subjects recently studied with yield stress fluids include: Suspension flows, Wavy-walled channels and fouling, Shear instabilities, Rayleigh-Bénard flows, Bubble propagation, particle sedimentation, visco-plastic lubrication, miscible displacement flows. Research in these areas is ongoing.
  • Industrial mathematical modelling: This work is industry-driven. Broadly, I have been interested in processes combing thermal and fluid dynamic effects. Examples: oilfield cementing, spray deposition/forming, injection molding, continuous casting, Czrochalski crystal growth, image processing, wellbore hydraulics, slurry transport, well control.

Current Research Work

  • Non-Newtonian fluid mechanics: Subjects recently studied with yield stress fluids include: Shear instabilities, Rayleigh-Bénard flows, Bubble propagation, particle sedimentation, visco-plastic lubrication, miscible displacement flows, dispersion, Taylor-Couette instabilities, regularization methods. Research in these areas is ongoing.
  • Industrial mathematical modelling: Subjects recently studied include: InSb crystal growth, injection molding, reactive displacement flows, waxy crude oil pipeline restarts, cementing displacement flows.
