We examine the transient evolution of a negatively buoyant, laminar plume in an emptying filling box containing a uniform porous medium. In the long time limit, τ→∞, the box is partitioned into two uniform layers of different densities. However, the approach towards steady state is characterized...
Heterogeneous materials are omnipresent in several critical engineering applications such as polymer electrolyte fuel cells (PEFCs), coal bio-conversion process, geological storage of CO2 and membrane water filtration. These applications rely on physical processes such as transport (e.g., mass,...
Quantification of transport properties at pore scale is important for efficient oil extraction, improving fuel cell performance etc. An experimental methodology is developed for calculating permeability and porosity in microfluidic devices that contain structured and unstructured porous media....
This thesis studies operator splitting for flow equation coupled to a transport equation arising from two-phase (water-oil) model in reservoir simulation. We apply two different types of operator splittings and compare their accuracies. Summarized scheme and alternating triangle method (ATM) in...
Aiming to pursue studying enhanced oil recovery processes with an ex-situ produced emulsion as flooding agent, an improved core flooding experimental system was designed, constructed and commissioned. The developed system allows the use of not only emulsion, but also other flooding agents,...
Mass transfer at an organic solid – organic liquid interface within reservoir rock under creeping flow conditionsDownload
There is a growing recognition that knowledge gaps related to the molecular and phase state complexity of hydrocarbon resources, and their interactions within production and processing environments have begun impeding development of new or improved processes that protect the natural environment...
Drawing on ideas from turbulent plume theory, a novel solution is presented for buoyant convection from an isolated source in uniform and non-uniform porous media of finite extents. In the former case, the problem is divided into three flow regimes: (i) a negatively-buoyant plume, (ii)...
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...
Beyond Viscosity—How Density, Vibration and Interfacial Tension Affect Solvent Aided Bitumen ProductionDownload
Bitumen and heavy oil comprise a significant percentage of proven oil reserves globally. The environmental impacts of producing these resources with current technologies is a concern for environmentalists, oil producing companies, resource rich jurisdictions and society at large. Dilution of the...
One of the central puzzles concerning the interaction of low Reynolds number (Re<<1) fluid transport with bacterial biomass is the formation of filamentous structures called bacterial streamer. Bacterial streamers can be tethered at one or both ends to solid surfaces, while the rest of the...
