Spring 2013
Removal of a drop from its substrate may be gradually (e.g. evaporation) or all at once (e.g. shedding). In this thesis, drop adhesion force as a base for understanding the all at once removal of a drop from its substrate, and drop evaporation in room temperature as one of the gradual removal...

Dynamics of spontaneous initial spreading and spreading of a hydrodynamically driven droplet under the influence of surrounding pressure
DownloadFall 2021
We investigate experimentally the early time dynamics of spontaneous spreading of silicone oils with various viscosities at elevated surrounding pressures. The surrounding medium pressure is increased in a monotone fashion starting from atmospheric pressure to a maximum value of 30 megapascal...

Fabrication and Characterization of Photolithographically Patterned Rough Surfaces Demonstrating Extreme Contact Angle Behavior
DownloadFall 2014
This thesis features experimental work done to fabricate and characterize silicon surfaces patterned using photolithographic techniques, both standard and novel, to produce a variety of surfaces with roughness of controlled geometric properties. In specific, one set of the surfaces fabricated...

Hydrogen can be produced from biomass; this hydrogen is called biohydrogen. Biohydrogen produced in Western Canada can partially contribute to meeting the demand for hydrogen needed for bitumen upgrading. Gasification and pyrolysis are two promising pathways for producing biohydrogen in a...

Drop transfer from one solid surface to another through stretching liquid bridges between them is important for many industrial applications. Due to the different dominate forces, three possible regimes exist: Quasi-static Regime, where the transfer process is only dominated by surface forces;...

This work focuses on validation of a commercial computational fluid dynamics (CFD) software ANSYS Fluent 16.2 applied to multi-phase modeling of fluidized beds. A two-phase Eulerian-Eulerian based model is used to numerically reproduce experiments carried out by Taghipour, F. et al (Chem. Eng....

Rheological behavior and nano-microstructure of complex fluids: Biomedical and Bitumen-Heavy oil applications
DownloadFall 2010
The main objective of this research was to exploit the interrelations between the rheological behavior and nano-microstructure of complex fluids in solving two state-of-the-art problems, one in the field of biomedical engineering: controlling the amount and characteristics of bioaerosol droplets...

Effect of rotation on dynamcis of flow in microchannels is studied. In the frist study, an analytical solution is developed for the unsteady flow of fluid through a parallel rotating plate microchannel, under the influence of electrokinetic force using the Debye–Hückel (DH) approximation....
