Effective and accurate model dynamics, deterministic and stochastic, across multiple space and time scales. A persistent feature of complex systems in engineering and science is the emergence of macroscopic, coarse grained, coherent behaviour from the interactions of microscopic agents (molecules, cells, grains) and with their environment.

A persistent feature of complex systems in engineering and science is the emergence of macroscopic, coarse grained, coherent behaviour from the interactions of microscopic agents (molecules, cells, grains) and with their environment. In current modeling, ranging from ecology to materials science, the underlying microscopic mechanisms are often known, but the closures to translate microscale knowledge to a system level macroscopic description are rarely available in closed form. Our novel methodology will explore this stumbling block, and promises to radically change the modeling, exploration and understanding of multiscale complex system behaviour.Read moreRead less

Physics of Risk: new tools to survey the Australian market and beyond. The lives of most Australians depend on the dynamics of financial markets that affects investments, savings, business, employment, growth, wealth and -ultimately- the daily functioning of our society. Understanding, monitoring and managing the dynamics of financial markets is of crucial importance to policy-makers, financial institutions and businesses that are increasingly faced with managing risk, planning strategies and ta ....Physics of Risk: new tools to survey the Australian market and beyond. The lives of most Australians depend on the dynamics of financial markets that affects investments, savings, business, employment, growth, wealth and -ultimately- the daily functioning of our society. Understanding, monitoring and managing the dynamics of financial markets is of crucial importance to policy-makers, financial institutions and businesses that are increasingly faced with managing risk, planning strategies and taking decisions in an increasingly complex market-place. The project is also of importance to the continued evolution of physics in this country contributing to the emergence of a strong new area of statistical physics concerned with the ?real world? in a manner hitherto unknown.Read moreRead less
Multi-Group Stochastic Modelling of Population Balance for Gas-Liquid Flows. Multiphase flow systems are encountered in many process industries such as chemical, petroleum, mining, nuclear, energy, food and pharmaceutical, which are fundamental to the Australian economy. Commercially available computer codes for simulating such systems are currently widely used in many Australian industrial sectors. This research project will address the prevalent deficiency in many of these computer codes and ....Multi-Group Stochastic Modelling of Population Balance for Gas-Liquid Flows. Multiphase flow systems are encountered in many process industries such as chemical, petroleum, mining, nuclear, energy, food and pharmaceutical, which are fundamental to the Australian economy. Commercially available computer codes for simulating such systems are currently widely used in many Australian industrial sectors. This research project will address the prevalent deficiency in many of these computer codes and develop new models capable of predicting a wide range of industrial bubbly flow problems. The resultant improved computer codes will provide industries with significant benefits and, in particular, reduce times and costs in their design and production. Read moreRead less
Solidification, Channel Formation and Thermal Erosion In Lava Flows. This project will elucidate the complex dynamics that control the cooling rates and advance rates of lava flows. It will result in improved hazard assessments for volcanic areas around the world affected by the advance of lava flows, including many Pacific islands and most countries around the Pacific Rim. The project will also provide a quantitative understanding of thermal erosion in lava channels, which will help explain th ....Solidification, Channel Formation and Thermal Erosion In Lava Flows. This project will elucidate the complex dynamics that control the cooling rates and advance rates of lava flows. It will result in improved hazard assessments for volcanic areas around the world affected by the advance of lava flows, including many Pacific islands and most countries around the Pacific Rim. The project will also provide a quantitative understanding of thermal erosion in lava channels, which will help explain the formation and location of major ore deposits of nickel, copper and platinum in Western Australia and elsewhere around the world.Read moreRead less
The Fluid Dynamics of Lava Flows: Silicic Domes and Basaltic Channels. Lava flows surface much of the Earth, Moon and terrestrial planets. This interdisciplinary program will combine laboratory experiments, mathematical analysis, numerical modelling and field observations to elucidate the complex dynamics of lava flows, including the nonlinear coupling of flow with surface solidification and basal melting. The focus will be on lava dome instability, and flow in open channels and tubes. Expected ....The Fluid Dynamics of Lava Flows: Silicic Domes and Basaltic Channels. Lava flows surface much of the Earth, Moon and terrestrial planets. This interdisciplinary program will combine laboratory experiments, mathematical analysis, numerical modelling and field observations to elucidate the complex dynamics of lava flows, including the nonlinear coupling of flow with surface solidification and basal melting. The focus will be on lava dome instability, and flow in open channels and tubes. Expected outcomes include: the ability to predict rates of lava flow cooling and advance, indicators of hazardous lava dome collapse, improved volcanic hazard assessments, explanations of the genesis of world-class magmatic ore deposits, and new interpretations of planetary surface morphologies.Read moreRead less

Nucleosynthesis today and tomorrow. Australia is a recognised world leader in understanding the interiors of stars and how they make the elements seen all around us, from Carbon to Gold and beyond. This project combines Australian theoreticians with the world's largest telescopes and computers, as well as the latest laboratory instruments and techniques, to further our understanding of where all the elements originated.
The role of magnetic fields in star formation. Recently we have performed the world's first calculations of star cluster formation that incorporate the effects of magnetic fields and radiation. This research has recently been brought back to Australia and the goal of this proposal is to extend our competitive edge in this area.

This research has recently been brought back to Australia and the goal of this proposal is to extend our competitive edge in this area.
Whilst calculations of the formation of stars gives us fundamental understanding about a very basic physical process in the universe (namely, the conversion of gas into stars), the equations we solve and the methods used to solve them, are the same as those used to describe many gases and fluids on earth. Solving these equations in difficult astrophysical regimes develops new methodology which translates readily to earth-bound problems.Read moreRead less
