Current Research Work

Liquid sprays:
In collaboration with LB Foster, fundamental studies of the flow of  Newtonian and non-Newtonian liquids in a pressure atomizer and the interaction of the liquid column with a moving surface have been performed. These studies have aided LB Foster in developing the next generation of railroad friction modifier, which will improve train fuel economy and reduce rail maintenance.

Papermaking:
Paper is formed by taking a very dilute suspension of pulp fibres and hydrodynamically filtering the suspension, thus producing a mat of fibres. In collaboration with AstenJohnson we have studied various aspects of papermaking. The goal of this research is to develop a model of the fibre deposition and dewatering process.

Biomechanics:
Professor Fels from Electrical  Engineering, various graduate students, and I are working to develop a computer model of liquid and gas flow in the upper airway. The purpose of this work is to guide surgeons on best practices for reconstructive surgery of the airway.

Building Ventilation
In  collaboration with Professor Rogak, Stantec, the Vancouver Airport Authority, and CIRS (Centre for Integrated Research on Sustainability), building ventilation and filtration are being studied.These studies have provided insight into optimal design of displacement ventilation systems and air handling equipment.
