This project aims to predict the performance and scalability of viscous transfer turbines. The work will be carried out with Micromachines Ltd., a firm developing working turbines with 50 mm rotors. The goal of the research is to gain an understanding of the scaling laws for these turbines, in order to predict their performance. Viscous transfer turbines have a very simple disc construction making them ideal for manufacturing as small-scale units (with a 5 mm rotor). Small enough to replace batteries, but with a higher power output, they would provide the need for higher power output devices to replace batteries.Read moreRead less
Characterization of Fast Propagating Fires in Green Buildings. This project aims to gain a better understanding of the mechanisms of fast-propagating fires and to address the deficiency in current fire models in assessing the fire safety requirement of green buildings.

This project aims to gain a better understanding of the mechanisms of fast-propagating fires and to address the deficiency in current fire models in assessing the fire safety requirement of green buildings. Although there are many compelling advantages associated with green building designs, because they promote better natural ventilation they could pose a significant fire hazard to occupants due to the propensity of rapid fire and smoke spread within the enclosed space. The new predictive fire model in this project is expected to promote a safer and sustainable building environment.Read moreRead less
