The increasing availability of plantation hardwood timber, with greater variability in its properties than previous resources, presents an opportunity to take advantage of the development of better mathematical techniques for process optimization and better drying and mechanical models for timber to address this challenge. This project will produce optimized drying schedules, which are combinations of temperatures and humidities used during drying, to effectively dry plantation timber with variable properties, producing timber for high-value and appearance-grade end uses, such as flooring and furniture.Read moreRead less
Exploiting Resonance in Improving Dried Timber Quality by Optimizing Cyclic Drying Processes in Solar Kilns. Maximizing the value of final dried timber is essential for maximizing the economic benefits for Australia. If 10% of one million cubic metres of sawn hardwood timber produced annually in Australia increases its value raised by $500/m3, then the potential direct gain to Australian companies is over A$50 million per year. Multiplier effects include future applications to the drying of fo ....Exploiting Resonance in Improving Dried Timber Quality by Optimizing Cyclic Drying Processes in Solar Kilns. Maximizing the value of final dried timber is essential for maximizing the economic benefits for Australia. If 10% of one million cubic metres of sawn hardwood timber produced annually in Australia increases its value raised by $500/m3, then the potential direct gain to Australian companies is over A$50 million per year. Multiplier effects include future applications to the drying of foods, where the potential benefit in using solar kilns is a reduction in CO2 emissions of at least a million tonnes of CO2 per year, and a potential cost reduction of A$38 million per year.Read moreRead less
Understanding and Controlling Wall Deposition in Spray Dryers via Experimental and Computational Fluid Dynamics (CFD) Studies. A key problem in operating spray dryers for producing milk powders and other consumer products, such as detergents, is the occurrence of internal wall deposits of powder, leading to thermal degradation of the products and potential fire hazards. However, no fundamental theory has been applied in spray dryers to allow this process to be controlled. The proposed project wi ....Understanding and Controlling Wall Deposition in Spray Dryers via Experimental and Computational Fluid Dynamics (CFD) Studies. A key problem in operating spray dryers for producing milk powders and other consumer products, such as detergents, is the occurrence of internal wall deposits of powder, leading to thermal degradation of the products and potential fire hazards. However, no fundamental theory has been applied in spray dryers to allow this process to be controlled. The proposed project will use state-of-the-art experimental and computational techniques to gain a fundamental understanding of this phenomenon and will develop a validated wall deposition model to predict when and to what extent this process occurs, to give higher throughputs and/or more efficient systems.Read moreRead less

Development of an integrated methodology to assess dewatering system performance in solid-liquid separation. 3D visualisations of microstructures are possible with techniques such as confocal laser microscopy and high resolution X-ray microtomography. Data obtained in-situ enable direct computation of solids assembly properties and their permeability to fluids. A specific application involving aggregate formation and sediment networks could be evaluated through micro-scale analysis combined with ....Development of an integrated methodology to assess dewatering system performance in solid-liquid separation. 3D visualisations of microstructures are possible with techniques such as confocal laser microscopy and high resolution X-ray microtomography. Data obtained in-situ enable direct computation of solids assembly properties and their permeability to fluids. A specific application involving aggregate formation and sediment networks could be evaluated through micro-scale analysis combined with robust fluid flow simulations. The method can potentially be utilized to predict trends such as filtration behaviour of materials under different states of compression. This offers significant benefits in formulating the design of flocculated systems pertinent to a number of industrial sectors wishing to design optimum solid-liquid separation processes.Read moreRead less

Electrocoagulation as a low-cost option for the continuous treatment of highly polluted wastewater. Water is a critically important 'raw material' with less than 0.01% of Earth's total supply being readily available. 'Once through' utilisation of this resource is no longer an acceptable industrial practise. Recycling/reuse of industrial wastewater must become the norm with economic pollutant recovery being seen as integral to the solution. The food/beverage industries are major water users.

Water is a critically important 'raw material' with less than 0.01% of Earth's total supply being readily available. 'Once through' utilisation of this resource is no longer an acceptable industrial practise. Recycling/reuse of industrial wastewater must become the norm with economic pollutant recovery being seen as integral to the solution. The food/beverage industries are major water users. Detailed scoping work in 2005 has identified electrocoagulation as a technically simple and economically viable option for this industry sector. Our industry partner is part of a global multi-national corporation within which successful wastewater treatment technology will be rapidly exploited and exported. Read moreRead less
