Dr. Penney’s primary research interests are in fluid mixing and process development and design. In the area of fluid mixing, Dr. Penney has investigated several phenomena including:

  • feedpipe backmixing in agitated reactors
  • scaleup methods for fast competitive reactions in agitated vessels
  • static mixers in recycle loops on agitated vessels to improve fast competitive reaction yields
  • interstage backmixing in compartmented mechanically-agitated staged columns
  • flooding in compartmented mechanically-agitated staged columns
  • vortex formation in partially-baffled agitated vessels
  • just suspended speeds for liquid-liquid dispersion in agitated vessels
  • solids suspension in agitated vessels
  • surface profiles, compartmental fractional fillage and mass transfer in a Vickers-Zimmer style polyester finisher
  • scaleup methods for fast reactions in pipeline mixers

He directed a DOE funded research program which developed a feasible process for recovering bitumen from tar sands.
