Multiscale modelling and analysis of complex particulate and multiphase flow. Particulate and multiphase processes are widely used in both conventional and modern industries in Australia and worldwide, however rarely reach more than 60% of design capacity because of a poor understanding of their fundamental characteristics. This frontier technology research program aims to overcome this problem using an extensive combined fundamental and applied approach.

Particulate and multiphase processes are widely used in both conventional and modern industries in Australia and worldwide, however rarely reach more than 60% of design capacity because of a poor understanding of their fundamental characteristics. This frontier technology research program aims to overcome this problem using an extensive combined fundamental and applied approach. The resulting theories, computer models and simulation techniques will be applied to improve process design, control and optimisation. Consequentially, productivity and Australian competitiveness will be significantly enhanced in its most important industries such as minerals, metallurgical, chemical, energy, pharmaceutical and materials.Read moreRead less

This will be achieved through detailed analysis of the particle-particle and particle-wall interactions at both microscopic and macroscopic levels, supported by the newly developed averaging theory and novel discrete particle simulation.

This project aims to understand and provide computational design tools for the complex heat and mass transfer processes within the new technologies that needed for the high temperature processing of minerals with low net carbon dioxide (CO2) emissions, both with and without the use of concentrated solar thermal energy. These models are needed to achieve low-cost scale-up and development of the new technologies under development, because they operate in regimes of particle-laden flow for which present numerical design tools are unreliable. The project will underpin the development of new technologies that are needed for Australia to meet its greenhouse emissions targets and to capitalise on the anticipated global demand for low-carbon-intensive metals and other value-added products.Read moreRead less
