Tackling Atmospheric Chemistry Grand Challenges in the Southern Hemisphere. The project aims to provide a southern hemisphere perspective on current challenges in atmospheric chemistry: air quality, oxidation capacity, stratospheric change, and chemistry–climate interactions. Australia’s geographic position in the relatively clean southern hemisphere allows a unique opportunity to study environments with limited human influence, an opportunity that has largely been lost in the more populous nort ....Tackling Atmospheric Chemistry Grand Challenges in the Southern Hemisphere. The project aims to provide a southern hemisphere perspective on current challenges in atmospheric chemistry: air quality, oxidation capacity, stratospheric change, and chemistry–climate interactions. Australia’s geographic position in the relatively clean southern hemisphere allows a unique opportunity to study environments with limited human influence, an opportunity that has largely been lost in the more populous northern hemisphere. The intended outcomes of the project include validated ground-based and satellite datasets for monitoring Australia’s air quality, improved atmospheric models for predicting future atmospheric change, and a deeper understanding of the processes driving atmospheric composition worldwide.Read moreRead less
Gravity Current Driven Smoke Dispersion In a Stratified Ambient. Smoke from bushfires transported by gravity currents, and known to occur nationwide, caused the shutdown of businesses, education and events in Canberra in 2019. Recent scientific investigations have shown that the speed of propagation and concentration of smoke in these three-dimensional gravity currents have a long term ‘memory’ of their initial configuration. In this project, high-fidelity computational and experimental techniq ....Gravity Current Driven Smoke Dispersion In a Stratified Ambient. Smoke from bushfires transported by gravity currents, and known to occur nationwide, caused the shutdown of businesses, education and events in Canberra in 2019. Recent scientific investigations have shown that the speed of propagation and concentration of smoke in these three-dimensional gravity currents have a long term ‘memory’ of their initial configuration. In this project, high-fidelity computational and experimental techniques will be used to elucidate the fundamental mechanisms of gravity current entrainment and propagation. This knowledge will set a strong foundation to improve operational forecasts of smoke transport that will allow government agencies to better respond to the negative impact of these complicated flows.Read moreRead less

Development of engine management systems for turbocharged gasoline direct-injection engines with optional natural gas port-injection. This project aims to develop universal and programmable engine management systems for gasoline direct-injection engines with lean-burn technology and optional natural gas port-injection.

This project aims to develop universal and programmable engine management systems for gasoline direct-injection engines with lean-burn technology and optional natural gas port-injection. The new engine management system will enable higher fuel efficiency than its predecessors and the increased use of nationally-produced natural gas. The project aims to overcome three main problems that limit efficiency improvement of direct-injection engines, namely: misfiring, unstable combustion, and soot emission. How these issues are impacted by additional natural gas port-injection will also be explored. This project aims to accomplish this by combining fundamental in-cylinder optical measurements and detailed modelling.Read moreRead less
