High value micron-sized particles from a novel antisolvent vapour spray drying system. Convective antisolvent precipitation is a novel route in producing particles from spray drying by adding an anti-solvent to the drying medium. This project will allow conventional spray dryers to produce more sophisticated ultrafine and encapsulated particles for use in food, pharmaceuticals and other high value applications.
Micromechanical analysis of size segregation and its prediction in granular free-surface flows. Industries often suffer from size segregation in the handling and processing of granular materials, leading to significant economic consequences. This project aims to develop a fundamental understanding of size segregation and prediction models, enabling industries to eliminate, minimise, or manage the effects to an acceptable level.

Perfect particles: Accurate breakage predictions by 3D printing of granules. Granule breakage of micro-structured specialty products impedes manufacturing and degrades product performance. Predictive breakage models have had limited success as each granule has a unique structure. Differences between the model predictions and experimental breakage test results could be due to inaccurate models or irreproducible experimental results due to granule structure differences. This project is expected to ....Perfect particles: Accurate breakage predictions by 3D printing of granules. Granule breakage of micro-structured specialty products impedes manufacturing and degrades product performance. Predictive breakage models have had limited success as each granule has a unique structure. Differences between the model predictions and experimental breakage test results could be due to inaccurate models or irreproducible experimental results due to granule structure differences. This project is expected to be the first ever application of three-dimensional printing for reproducible breakage testing. The project aims to: create the first ever multiple identical copies of complex granules using polyjet three-dimensional printing; model and experimentally measure granule breakage; and develop sophisticated Digital Elevation Models of granule breakage for practical use in industry.Read moreRead less
