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
Quantitative and qualitative aspects of Asian and Australian options. While Asian options are highly popular and traded over the counter all over the world, they are traded on an institutional basis in only very few countries. Australia is one of them. Variable purchase options (VPO's), where the payoff is determined by the quotient of a stock and its average price, are traded on the Australian stock exchange since 1992. They build an important component of the Australian derivatives market and ....Quantitative and qualitative aspects of Asian and Australian options. While Asian options are highly popular and traded over the counter all over the world, they are traded on an institutional basis in only very few countries. Australia is one of them. Variable purchase options (VPO's), where the payoff is determined by the quotient of a stock and its average price, are traded on the Australian stock exchange since 1992. They build an important component of the Australian derivatives market and are particularly interesting for foreign investors, who are not able to find this sort of financial product on their domestic markets. A better understanding of these products is necessary to maximize the benefits for Australia's financial markets and economy. Read moreRead less
Improving the wool product. Using mathematical modelling to improve the efficiency of wool scouring. Our aim is to improve the quality of scoured wool by improving the efficiency of wool scouring. Wool scouring is the process of washing greasy wool once it has been removed from the sheep's back. After being rinsed to remove sweat and salt the wool is passed through a scour bowl consisting of settling tanks from which dirty water is periodically expelled. Mathematical modelling will optimise us ....Improving the wool product. Using mathematical modelling to improve the efficiency of wool scouring. Our aim is to improve the quality of scoured wool by improving the efficiency of wool scouring. Wool scouring is the process of washing greasy wool once it has been removed from the sheep's back. After being rinsed to remove sweat and salt the wool is passed through a scour bowl consisting of settling tanks from which dirty water is periodically expelled. Mathematical modelling will optimise use of the scour bowl, reduce consumption of water, increase the recovery of wool grease and improve the quality and cleanliness of the wool.Read moreRead less
Material boundaries in ultrasonics: New methods and in vitro studies in biomedical phantoms. Ultrasound is an indispensable part of healthcare worldwide. The next wave of applications will see ultrasound pulses used to closely probe suspected disease sites and to directly manipulate bioactive agents. For safe and effective use of such techniques it is essential to know the ultrasound field at the disease site. This project will develop simulation methods to achieve the fast, accurate and case-sp ....Material boundaries in ultrasonics: New methods and in vitro studies in biomedical phantoms. Ultrasound is an indispensable part of healthcare worldwide. The next wave of applications will see ultrasound pulses used to closely probe suspected disease sites and to directly manipulate bioactive agents. For safe and effective use of such techniques it is essential to know the ultrasound field at the disease site. This project will develop simulation methods to achieve the fast, accurate and case-specific results required. Community healthcare will benefit, through better diagnostic capabilities and customized treatment. Australia is well placed to profit further from this research, in view of the growing worldwide demand for more sophisticated, knowledge-based techniques in medicine.Read moreRead less
The effect of vessel wall structures on ultrasonic flow velocity measurements. The flow velocity within a nearly cylindrical vessel is often measured using an external ultrasound transducer via the Doppler principle. Thick vessel walls may present acoustically mismatched structures. This project aims to determine how such walls redistribute the energy in an interrogating ultrasound beam, and how this in turn affects the measurement of flow velocities. This is a fundamental issue, especially imp ....The effect of vessel wall structures on ultrasonic flow velocity measurements. The flow velocity within a nearly cylindrical vessel is often measured using an external ultrasound transducer via the Doppler principle. Thick vessel walls may present acoustically mismatched structures. This project aims to determine how such walls redistribute the energy in an interrogating ultrasound beam, and how this in turn affects the measurement of flow velocities. This is a fundamental issue, especially important in vascular disease where blood flow and blood vessels are affected by wall irregularities and lesions. The new knowledge generated by this project will have practical importance and, by identifying achievable outcomes, potentially major cost savings, in medical ultrasound.Read moreRead less
