A thorough understanding of slurry rheology is required for the design and computational fluid dynamics (CFD) simulation of slurry reactor to obtain optimal performance. A poorly designed reactor will have poor mixing, flow short circuiting and stagnant zones. This project will provide a means of characterising the ammonia phosphate slurry rheology on-line for WMC fertilizer plant, perform detailed rheological characterisation of the slurry with and without trace elements, and provide fluid flow behaviour within the reactor through CFD simulation. A mere 1% improvement over the current solids output of 100tonnes/hr will enhance the revenue by $2.5million/yr for WMC.Read moreRead less

Enabling the design of superior healthy snack foods and beverages through innovative assessment of oral processing and mucosal film interactions. Reducing sugar and fat in foods generally leads to products that are perceived as less flavoursome and appealing. A significant contributor to this is the interaction of foods and beverages with oral mucosal substrates, which play a key role in perceptual processes that drive unacceptable mouthfeel sensations. This project seeks to develop and use oral ....Enabling the design of superior healthy snack foods and beverages through innovative assessment of oral processing and mucosal film interactions. Reducing sugar and fat in foods generally leads to products that are perceived as less flavoursome and appealing. A significant contributor to this is the interaction of foods and beverages with oral mucosal substrates, which play a key role in perceptual processes that drive unacceptable mouthfeel sensations. This project seeks to develop and use oral mimetic substrates to permit objective and quantified rheological and tribological responses, imitating the underlying physics occurring during food oral processing that drive dynamic sensory responses. The project aims to enable a mechanism-based approach to minimise the amounts of fat, salt and sugar required for sensory properties that meet consumer expectations.Read moreRead less

Resolving nitrogen and phosphorus transformations along subterranean estuary - sediment/water interface continuums in carbonate sands. Humans are modifying global nitrogen (N) and phosphorus (P) cycles at an alarming rate. The release of N and P into the environment drives eutrophication, one of the greatest threats to coastal ecosystems worldwide. Globally, there is little effort being made to control increasing N and P emissions.

Humans are modifying global nitrogen (N) and phosphorus (P) cycles at an alarming rate. The release of N and P into the environment drives eutrophication, one of the greatest threats to coastal ecosystems worldwide. Globally, there is little effort being made to control increasing N and P emissions. The transport of contaminated groundwater is a major source of N and P to the coastal zone and an overlooked driver of eutrophication. Yet, research into the processes that influence N and P transformation in groundwater are scarce, they neglect carbonate sand systems and have ignored the processes in key groundwater transition zones. This project will generate new knowledge that will help us understand the role that groundwater plays in coastal eutrophication.Read moreRead less
Hydrogeological drivers and fate of spring flow in a semi-arid setting. In arid and semi-arid climates, aquatic and terrestrial ecosystems often rely on groundwater springs. Spring hydrology depends on complex relationships between underlying aquifers and surface conditions, leading to high uncertainties in understanding aquifer-spring-wetland hydrology, which is critical for spring ecosystem protection and to inform management of relevant groundwater-affecting activities. This project will appl ....Hydrogeological drivers and fate of spring flow in a semi-arid setting. In arid and semi-arid climates, aquatic and terrestrial ecosystems often rely on groundwater springs. Spring hydrology depends on complex relationships between underlying aquifers and surface conditions, leading to high uncertainties in understanding aquifer-spring-wetland hydrology, which is critical for spring ecosystem protection and to inform management of relevant groundwater-affecting activities. This project will apply novel hydrogeophysical and hydrochemical methods, and computer modelling, to investigate the source aquifer of, and fate of discharge from the Doongmabulla Springs Complex (DSC), located in an area of future development. Project results will inform spring vulnerability to development pressures and climate effects.Read moreRead less
Effect of cane sugar juice composition on scaling rate and scale composition in sugar mills. The Australia sugar industry produces 1100 GWh of renewable electricity annually, abating ~1.1 M tonnes of CO2-equivalent of greenhouse gases. This can be increased if the juice evaporation performance, which largely determines the energy efficiency of the sugar factory, can be improved through reduced fouling of evaporators. This project will investigate the effect of juice composition on fouling of sug ....Effect of cane sugar juice composition on scaling rate and scale composition in sugar mills. The Australia sugar industry produces 1100 GWh of renewable electricity annually, abating ~1.1 M tonnes of CO2-equivalent of greenhouse gases. This can be increased if the juice evaporation performance, which largely determines the energy efficiency of the sugar factory, can be improved through reduced fouling of evaporators. This project will investigate the effect of juice composition on fouling of sugar factory evaporators so that a model to predict scale type and scale propensity can be developed. This will enable the development of better scale control strategies, resulting in reduced energy usage and reduced usage of the hazardous and polluting chemicals required to remove scale.Read moreRead less
