This project aims to develop a novel process control approach that utilises big process data to improve the cost-effectiveness of industrial processes. Existing monitoring systems in the industry have been collecting a tremendous amount of process operation data but little effort has been made to use the big process data to enhance process operations. Based on the system behavioural approach and dissipativity theory, integrated with machine learning techniques, this project expects to develop a novel framework for data-driven control using big process data. The outcomes are expected to benefit the Australian process industry, where many processes are controlled by inadequate logic controllers, by improving their operational efficiency.Read moreRead less
Wet granule mechanics and their influence on agglomeration behaviour and granulation processes. Granulation is a widely-used particle size enlargement process performed by spraying a liquid binder onto an agitated powder mass. It is currently impossible to quantitatively predict granule growth behaviour in terms of the fundamental properties of the particles and binder. This project will measure and model the deformation of granules and the strength of bonds formed between them and use this info ....Wet granule mechanics and their influence on agglomeration behaviour and granulation processes. Granulation is a widely-used particle size enlargement process performed by spraying a liquid binder onto an agitated powder mass. It is currently impossible to quantitatively predict granule growth behaviour in terms of the fundamental properties of the particles and binder. This project will measure and model the deformation of granules and the strength of bonds formed between them and use this information to predict their growth behaviour. Special attention will be given to the effects of strain-rate and particle morphology in granulation mechanics. Improvements in granulation technology will be of great benefit to food, pharmaceutical, agricultural, explosives and mining industries and opens the way to 'designer granulation' for special purposes.Read moreRead less
