Elliptical nozzles: the shape of silence? This project aims to leverage the aeroacoustic properties of elliptical nozzle geometries to significantly reduce installed jet noise. This project expects to generate new knowledge regarding methods to reduce installed jet noise, a serious problem for the aerospace industry.

This project aims to leverage the aeroacoustic properties of elliptical nozzle geometries to significantly reduce installed jet noise. This project expects to generate new knowledge regarding methods to reduce installed jet noise, a serious problem for the aerospace industry. Regulatory constraints inhibit the implementation of efficiency-increasing configurations but still fail to eliminate public health impacts. Expected outcomes include a set of tools for optimizing nozzle designs capable of significantly reducing installed jet noise. This will provide significant benefits, as jet noise is a serious health issue for the Australian public. This project represents an opportunity to reduce its impact while improving fuel efficiency.Read moreRead less

Summary
Noise-reduction mechanisms in jet engines: chevrons are the answer. This project aims to develop new models to study the influence of chevrons on the exhaust of aircraft engines, which is one of the strongest sound sources during take-off. As constant exposure to high-amplitude noise in areas close to airports leads to a myriad of health problems, new strategies have been sought to mitigate this noise component. Chevrons may modify the dynamics of the noise-generating coherent structures, but mo ....Noise-reduction mechanisms in jet engines: chevrons are the answer. This project aims to develop new models to study the influence of chevrons on the exhaust of aircraft engines, which is one of the strongest sound sources during take-off. As constant exposure to high-amplitude noise in areas close to airports leads to a myriad of health problems, new strategies have been sought to mitigate this noise component. Chevrons may modify the dynamics of the noise-generating coherent structures, but most of their parameters are chosen by trial and error, and the mechanism that maximises noise reduction is not clear. By understanding the underlying noise-reduction mechanisms, this project will facilitate the optimal design of quieter exhaust nozzles, ameliorating the effect of aircraft noise on the local community.Read moreRead less
The Transitional and Turbulent Structure of Rotating Disk Boundary Layers. Design optimization in areas of energy, materials processing, manufacturing and aerodynamics often depends on fluid flows adjacent to surfaces (wall-flows), and many such flows are three-dimensional (3-D). At present, 3-D wall-flows are poorly understood, and thus we aim to provide the first comprehensive study of the prototypical 3-D wall-flow on a rotating disk. Experiments in a bespoke facility will cover the importan ....The Transitional and Turbulent Structure of Rotating Disk Boundary Layers. Design optimization in areas of energy, materials processing, manufacturing and aerodynamics often depends on fluid flows adjacent to surfaces (wall-flows), and many such flows are three-dimensional (3-D). At present, 3-D wall-flows are poorly understood, and thus we aim to provide the first comprehensive study of the prototypical 3-D wall-flow on a rotating disk. Experiments in a bespoke facility will cover the important flow regimes (transitional and turbulent), and novel sensors will quantify the detailed 3-D flow structure. By clarifying critical instability scenarios and revealing turbulent flow scaling structure, this project will fundamentally advance physical understanding and analytical and computational models of 3-D wall-flowsRead moreRead less
Community Self-determination in the Era of Automated Home Delivery Systems. Urban environments in Australia and internationally are on the cusp of major disruption resulting from impending proliferation of home delivery services using autonomous vehicles in the form of trucks, shuttles, bots, and drones. As witnessed in the case of ride-share services, socio-technical changes can permeate society before effective regulation is introduced unless swift anticipatory action is taken. The aim of this ....Community Self-determination in the Era of Automated Home Delivery Systems. Urban environments in Australia and internationally are on the cusp of major disruption resulting from impending proliferation of home delivery services using autonomous vehicles in the form of trucks, shuttles, bots, and drones. As witnessed in the case of ride-share services, socio-technical changes can permeate society before effective regulation is introduced unless swift anticipatory action is taken. The aim of this project is to deliver the critical information inputs required to empower and protect communities in a future characterised by the widespread use of automated product deliveries. Outputs will include modelled scenarios and negotiated policy recommendations that reflect meaningful community consultation.Read moreRead less

There is an acute deficiency of knowledge in Australia on urban airborne ultrafine particles, originating from transport and other anthropogenic sources, which pose significant health and environmental risks. The aim of this project is to address this deficiency by an extensive multi-city, cross-disciplinary study using state of the art instrumentation and data analytic techniques. The outcome will be an in depth, quantitative insight into the characteristics of the particles, their sources and spatial and temporal variation across different urban areas and time scales. Further, the impacts of changing fuels, vehicle technologies, and climate on future trends of the particles will be elucidated.Read moreRead less
