Engineering Department Executive Fluid Dynamics Oil Sands and Energy Surface Science and Engineering
I obtained my doctorate in Physics from the University of British Columbia in 1994. After working as a post-doctoral fellow for several years, I was hired by Syncrude Canada Ltd. as a Research Scientist. My research at Syncrude was focused on colloid and interface science, with applications to bitumen demulsification and froth treatment. I returned to academia in 2000, joining the Department of Chemical & Materials Engineering at the University of Alberta, and have been working here since.
Dr Yeung's chief research interests are the mechanics and thermodynamics of fluid-fluid interfaces, two-dimensional transport phenomena, and experimental studies on microscopic deformable surfaces. This work has application in the areas of emulsions, oil sands processing, macromolecules at fluid-fluid interfaces (e.g., water-based coatings, food colloids, biomembranes) and the attachment/transport of particulates at the oil water interface. Dr. Yeung is a project leader with the Centre for Oil Sands Innovation.
Principal Research Interest: Microinterfacial Phenomena
Physical systems of interest are deformable surfaces on the micrometre scale. In particular, we study:
Areas of Application
Many important systems in industrial and biological applications appear in the form of liquid-liquid dispersions, i.e., the dispersion of micrometre-sized liquid drops in a distinct (often immiscible) liquid. Examples of such heterogeneous systems include: emulsions, water-based latexes, biological cells, and microcapsules used in drug delivery. The most important attribute of any liquid-liquid dispersion is arguably its stability - that is, the ability of the dispersed droplets to resist coalescence and coagulation. Regardless of the specific application, the stability of any liquid-liquid dispersion is, without exception, controlled by the physical properties of the micrometre-scale interfaces. These interfaces will, in the present context, be referred to as microinterfaces.
Recent research had suggested that the physical properties of microinterfaces can be quite distinct from their macroscopic counterparts. As such, in situ studies on microinterfacial phenomena have become essential. Our research is focussed on the fundamentals of microinterfacial phenomena, based on rigorous principles of mechanics and thermodynamics. Equal emphasis will be placed on the theoretical and experimental aspects of this research.
