Multiphase flow

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…

In power generation from solid fuel such as coal-fired power plants, combustion efficiency can be monitored by the loss on ignition (LOI) of the pulverised fuel. It is the role of the pulveriser-classifier combination to ensure pulverised fuel delivered to the burners is within …
