This dissertation describes computational fluid dynamics (CFD) simulations of gas-solid flow in a riser and gas-liquid-solid flow in a slurry bubble column reactor. Three computer codes were used. The commercial code, Fluent, was used to simulate the dilute flow of 530 μm in the…

A pore-scale network model is developed to simulate formation and collapse of wetting and spreading oil layers in two- and three-phase flow systems. We focus mainly on oil layers and their connectivity at low oil saturations particularly in three-phase flow processes. A new conf…
The presence of subseismic scale faulting within high porosity sandstone reservoirs and aquifers represents a significant source of uncertainty for activities such as hydrocarbon production and the geologic sequestration of carbon dioxide. The inability to resolve geometrical pr…
