Experimentally validated theory for the mixing of granular materials. The project aims to develop better mixing theories to support industrial applications. Effective mixing of granular materials such as aggregates in building industry and stockpiles in mineral processing is important for creating homogeneous products, yet industrial mixers lack scientific design and operate with no control of mixture quality.

The project aims to develop better mixing theories to support industrial applications. Effective mixing of granular materials such as aggregates in building industry and stockpiles in mineral processing is important for creating homogeneous products, yet industrial mixers lack scientific design and operate with no control of mixture quality. The project aims to establish a new general continuum mixing theory, which will be validated against X-ray measurements of grain motions within small mixers. By describing the theory using an accurate computational method, the simulations of these mixers will be scalable, and would help deliver predictions for particle mixing in much larger operations. Other expected outcomes are to control mixture quality and reduce industry reliance on costly and time-consuming trial-and-error experiments.Read moreRead less

Engineering suspended particle sprays through controlled cavitation. This project aims to use cavitation to engineer particle size in sprays of micronised particles suspended in a propellant, and develop a physical mechanism for this process.

Understanding how cavitation affects the size of agglomerates in the liquid phase and droplet size in a spray is critical to developing spray devices that require precise control over the final particle size. This will be achieved through high-resolution optical imaging techniques and synchrotron X-ray diagnostics. This project is expected to provide physical insight with applications for inhaled and topical pharmaceutical sprays, and industry spray drying of food products.Read moreRead less

This state-of-the-art laser facility will increase our scientific understanding of industrial processes by providing valuable information on velocity, temperature and concentration profiles for rapidly changing flow fields. Previously it was not possible to do this, and the knowledge gained will be applied to develop more efficient and environmentally sustainable operations. For example, many current processes have high energy input but scientific evidence suggests that it can be reduced if the embodied energy of the flow is properly utilised. Importantly, this utilisation often leads to increased yields and product quality. The facility will greatly assist researchers and industry collaborators in developing processes for the 21st century.Read moreRead less
