Atomisation and Combustion Physics of Australian Bio-oils. Australia is highly dependent on fossil fuels for energy production and transport, and this dependence is growing. Wide spread substitution of liquid hydrocarbon fuels by indigenous renewable bio-oil has the potential to improve Australian's energy outlook and assist in reaching greenhouse gas targets. Understanding the interrelationships between the physical and chemical properties of bio-oil, its atomisation, droplet formation and com ....Atomisation and Combustion Physics of Australian Bio-oils. Australia is highly dependent on fossil fuels for energy production and transport, and this dependence is growing. Wide spread substitution of liquid hydrocarbon fuels by indigenous renewable bio-oil has the potential to improve Australian's energy outlook and assist in reaching greenhouse gas targets. Understanding the interrelationships between the physical and chemical properties of bio-oil, its atomisation, droplet formation and combustion physics is fundamental to the delivery of an efficient and reliable combustion process using this fuel. Measurements using laser based diagnostics of the atomisation flow, droplet formation and combustion process will provide the experimental data to understand this complex interrelationship.Read moreRead less
Quantifying the role of the Southern Ocean for anthropogenic CO2 uptake. Carbon dioxide (CO2) is the most important greenhouse gas contributing to global warming and climate change. Climate change is likely to have dramatic economic and environmental consequences for Australia. Knowledge and understanding of the complex carbon cycle is fundamental for predicting future atmospheric CO2 levels and managing climate change. The aim of the work proposed here is to quantify and improve our understan ....Quantifying the role of the Southern Ocean for anthropogenic CO2 uptake. Carbon dioxide (CO2) is the most important greenhouse gas contributing to global warming and climate change. Climate change is likely to have dramatic economic and environmental consequences for Australia. Knowledge and understanding of the complex carbon cycle is fundamental for predicting future atmospheric CO2 levels and managing climate change. The aim of the work proposed here is to quantify and improve our understanding of the oceans role in controlling atmospheric CO2 levels. This will be done by combining modeling and observational expertise among UNSW and CSIRO (Marine Research) researchers. Our work will be the first to assess the extent of which the Southern Ocean (and Australian waters) acts as a carbon sink. This will reduce modeling uncertainties in predicting future atmospheric CO2 levels and will also be valuable to the federal government in future international negotiations on climate change.Read moreRead less
Fundamental studies of the packing and compaction of fine particles. This project will investigate the fundamentals of the packing and compaction of fine particles at both microscopic and macroscopic levels through a combined theoretical and experimental program. It involves the use of advanced techniques to generate particle scale information, so that a packing and compaction process can be assessed at various time and length scales. It will produce a comprehensive understanding of the underlyi ....Fundamental studies of the packing and compaction of fine particles. This project will investigate the fundamentals of the packing and compaction of fine particles at both microscopic and macroscopic levels through a combined theoretical and experimental program. It involves the use of advanced techniques to generate particle scale information, so that a packing and compaction process can be assessed at various time and length scales. It will produce a comprehensive understanding of the underlying physics, computer models capable of predicting the micromechanic and transport properties of porous media, and an effective means to solve many packing and compaction problems widely encountered in minerals and materials processing industries.Read moreRead less
