SESM6040 Thermofluid Engineering for Low Carbon Energy

Module Overview

Hydrocarbon fuels contribute more than 85% of world energy production, but also contribute more than 60% of anthropogenic greenhouse gas emissions. As research continues to find alternative and more sustainable energy production technologies hydrocarbon fuels will continue to be the primary energy supplier therefore measures need to be taken to improve their efficiency and minimise anthropogenic greenhouse gas emissions. This module addresses thermo-fluid processes underlying technologies which use hydrocarbon fuels in a more sustainable manner, including clean combustion, carbon capture and storage, enhanced oil and gas recovery. To enable students to develop technology for these applications, this module equips students with physical insight and engineering methods for heat and mass transport, chemically-reacting flows, multi-phase flows, and porous media flows.
