Understanding extreme wind gusts and associated risks in NSW. Wind gusts are rare bursts of high wind, often associated with thunderstorm outflows. They can do significant structural damage, and their rarity and small scale make prediction and risk assessment difficult. This proposal seeks to better understand and predict wind gusts and their impacts to aid in planning. The project aims to use past observations, modelling, and basic theory to show what conditions lead to wind gusts and how like ....Understanding extreme wind gusts and associated risks in NSW. Wind gusts are rare bursts of high wind, often associated with thunderstorm outflows. They can do significant structural damage, and their rarity and small scale make prediction and risk assessment difficult. This proposal seeks to better understand and predict wind gusts and their impacts to aid in planning. The project aims to use past observations, modelling, and basic theory to show what conditions lead to wind gusts and how likely they are to exceed key thresholds. It targets important scientific and practical issues such as the joint occurrence of gusts and high rainfall, role of gusts in contributing to dust and other airborne pollutants, impacts of gusts on subsequent storm activity, and gusts in a warming climate.Read moreRead less
High performance electrolyte for the vanadium redox flow battery. Vanadium batteries present a highly-scalable, sustainable solution for storage of renewable electricity, but the technology needs to be improved for robust and efficient operation in the warm Australian climate. This project aims to design and extensively test new high-performance electrolyte compositions with advanced thermal stabilising additives for safe long-term battery operation at 60 °C.

Electron Transpiration Cooling of Hypersonic Vehicles. Future aircraft for flight at hypersonic speeds require sharp leading edges for the best aerodynamic performance. Sharp leading edges incur high heat loads and cannot be adequately cooled with current technologies. The project aim is to investigate novel surface materials that emit electrons when heated. This emission of electrons from the surface can significantly contribute to the cooling of the sharp leading edges. This project is expecte ....Electron Transpiration Cooling of Hypersonic Vehicles. Future aircraft for flight at hypersonic speeds require sharp leading edges for the best aerodynamic performance. Sharp leading edges incur high heat loads and cannot be adequately cooled with current technologies. The project aim is to investigate novel surface materials that emit electrons when heated. This emission of electrons from the surface can significantly contribute to the cooling of the sharp leading edges. This project is expected to deliver new experimental data on novel surface materials exposed to a hypersonic flow environment and computer models that can simulate their cooling effect. This investigation will contribute towards enabling technologies for sustained hypersonic flight by overcoming critical head load limitations.Read moreRead less
Structural Reliability of Engineering Structures in Cyclonic Winds. This project aims to address the challenge of predicting the impact of extreme cyclonic winds on complex engineering structures.
