Turbulent flow over surfaces with spatially varying roughness. This project aims to improve understanding of the effect of spatial roughness transitions on turbulent flows. Fluids flowing over non-smooth surfaces influence our daily lives, such as water moving through a pipe, wind blowing over the Earth's surface or aircraft moving through air. The presence of surface roughness profoundly influences these flows. Though engineers have learnt to deal effectively with evenly distributed roughness, ....Turbulent flow over surfaces with spatially varying roughness. This project aims to improve understanding of the effect of spatial roughness transitions on turbulent flows. Fluids flowing over non-smooth surfaces influence our daily lives, such as water moving through a pipe, wind blowing over the Earth's surface or aircraft moving through air. The presence of surface roughness profoundly influences these flows. Though engineers have learnt to deal effectively with evenly distributed roughness, this is seldom encountered in reality. Rather, there are abrupt changes in roughness, for example at the edges of wind-farms or at rivets on aircraft. This project aims to investigate these important, but little understood, turbulent flows. Potential benefits include improved simulation, more efficient vehicle design and improved atmospheric and climate models.Read moreRead less

Summary
Life cycle assessment of greenhouse gas emissions for road infrastructure. This project aims to develop an assessment model to accurately measure greenhouse gas emissions that roads generate over their life cycle. The project will integrate recent methodological developments and practical advances from road construction and maintenance into its proposed assessment model. The expected outcome will be an assessment model and mapping tool which will visualise emissions levels and better map these e ....Life cycle assessment of greenhouse gas emissions for road infrastructure. This project aims to develop an assessment model to accurately measure greenhouse gas emissions that roads generate over their life cycle. The project will integrate recent methodological developments and practical advances from road construction and maintenance into its proposed assessment model. The expected outcome will be an assessment model and mapping tool which will visualise emissions levels and better map these emissions into the cost-benefit analysis of roads. This will make greenhouse gas reduction more effective and cheaper, and make the Australian infrastructure sector more competitive.Read moreRead less
Lower greenhouse at lower cost: maximising the potential of liquefied petroleum gas (LPG) in passenger vehicles. This project will develop tools for designing internal combustion engines that simultaneously achieve low greenhouse emissions without added consumer cost. The project aim is to be achieved through the effective use of liquefied petroleum gas (LPG), which is an affordable fuel that has potentially low emissions if used properly.
Locating jobs to improve urban sustainability: investigating the Transport Impacts of Employment Decentralisation in Australian Cities (TIEDAC). This project investigates how the relocation of public sector employment to suburban nodes can improve the efficiency of Australian cities. The project will identify transport efficiencies from employment decentralisation that can reduce infrastructure costs for governments and reduce commuting distances for Australian urban residents.
Making best use of biofuels – understanding the interactions between alcohol and hydrocarbon fuels in engine combustion. Biofuels are increasingly used as blending components for transport fuels. Biofuels possess much different chemical structures from conventional fuels, and can therefore interact with hydrocarbon fuels during engine combustion processes and consequently affect engine efficiency and emissions. This project aims to investigate the chemical interactions between representative com ....Making best use of biofuels – understanding the interactions between alcohol and hydrocarbon fuels in engine combustion. Biofuels are increasingly used as blending components for transport fuels. Biofuels possess much different chemical structures from conventional fuels, and can therefore interact with hydrocarbon fuels during engine combustion processes and consequently affect engine efficiency and emissions. This project aims to investigate the chemical interactions between representative compounds of biofuels (ethanol) and fossil fuels (n-heptane, iso-octane and toluene) during engine autoignition processes. The outcomes will fill a significant gap in our understanding for biofuel combustion chemistry, essential for building predictive combustion models, and will guide the best use of the precious Australian biofuel resources to reduce carbon dioxide emissions.

This project aims to clarify the mechanism of power losses in magnetic cores used in the petrol-electric hybrid cars by investigating the relationship between the core losses and magnetic correlation lengths in iron alloys. This project expects to generate new knowledge on the effect of magneto-mechanical interaction on the anomalous core loss in iron based alloys. The intended outcomes include an experimental confirmation of the random anisotropy model, a major theoretical model in nanostructured materials and identification of ideal magnetic domain configurations for lower power losses. These intended outcomes should bring great benefits to the development of low-carbon vehicle technologies for sustainable motorisation in Australia.Read moreRead less

Economically efficient green logistics through cyber physical systems. This project aims to realize green logistics by researching how to run diesel-powered heavy-duty milk trucks economically and efficiently on liquefied natural gas (LNG) and demonstrating to logistics companies that LNG conversion will reduce operating costs and emissions. Transportation systems account for 18% of Australia's carbon emissions, and diesel-powered logistics vehicles are a major contributor. However, converting these trucks to LNG requires strong evidence to convince logistics companies of the benefits of shifting to green logistics. An increase in logistics productivity is expected to increase Australia’s gross domestic product by $2 billion, while this research should also provide vital data on sustainability issues and LNG conversions.Read moreRead less

This project aims to quantify and understand how future, advanced passenger vehicles might perform when optimised for the direct injection (DI) of natural gas. Such production vehicles do not exist, largely because production DI systems for natural gas, spark ignition engines are not yet available. This project will examine both advanced conventional and hybrid vehicles using a suite of state-of-the-art experimental and numerical techniques. This project will quantify these vehicles’ environmental, technical and economic performance to determine whether DI natural gas, conventional and hybrid vehicles might reduce substantial greenhouse gas (GHG) emissions whilst avoiding any consumer penalty. This research could contribute to global GHG abatement.Read moreRead less
