The effect of buoyant convection on the buoyancy-driven spreading and draining of porous media gravity currents along a permeability jump
DownloadSpring 2022
We investigate theoretically the impact of introducing convective dissolution along the interface of a (dense) miscible gravity current propagating up- and downdip along a permeability jump in a saturated, layered porous medium. Emphasis is placed on three different dissolution scenarios, namely...

The size distribution, volatile mass fraction, effective density, mass concentration and mass-mobility exponent of particles from an inverted burner and a McKenna burner were measured with a Differential Mobility Analyzer (DMA) and a Centrifugal Particle Mass Analyzer (CPMA). Based on these...

This thesis describes an investigation of gravity currents, which are buoyancy-driven horizontal fluid flows. In particular this work reports upon a series of laboratory experiments and complementary (two-dimensional) direct numerical simulations that explore the lock release of a fixed volume of...

Cable shovels are mostly used as primary equipment in large-scale surface mining operations. A single unexpected component failure could cause unforeseen costly shutdowns, reduced productivity and may even pose a great danger to on-site personnel. The ideal maintenance strategy is to reveal...

Assessment of Greenhouse Gas Emission Mitigation Potential and Abatement Costs of Alternative Technology Options for Oil Sands
DownloadSpring 2020
In the last several decades societies have gained an increasing level of awareness and scientific understanding of the impact of anthropogenic greenhouse gas (GHG) emissions on average global temperatures and the negative results of those temperatures increasing. Many governments, including...

Experimental and theoretical investigation of mass transport in porous media of a PEM fuel cell
DownloadFall 2011
Porous media is an integral part of polymer electrolyte fuel cell (PEMFC) electrodes. In this study, an experimental setup is presented to investigate convective and diffusive mass transport in porous media of fuel cell electrodes. A new theoretical model was developed in order to correct for...
