Granular dynamics: from discrete simulation towards continuum modelling. The project aims to develop a general averaging theory to link discrete to continuum description of granular dynamics and a comprehensive understanding of the underlying physics. 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. The result ....Granular dynamics: from discrete simulation towards continuum modelling. The project aims to develop a general averaging theory to link discrete to continuum description of granular dynamics and a comprehensive understanding of the underlying physics. 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. The results, in terms of constitutive relations and boundary conditions, will be implemented in continuum-based process modelling and tested by comparing numerical and experimental results via typical case studies. It will significantly enhance the present capability of modelling granular flow that is widely encountered in many industries and in nature.Read moreRead less
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. The resulting theories, computer models ....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. 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
Numerical and experimental studies of the gas-particle flow and dust collection in electrostatic precipitation systems. This project will generate an integrated computer model to describe the gas-solid flow and dust collection in an ElectroStatic Precipitator (ESP). The model can be used to aid the design and control of ESP systems which are widely used for dust collection, leading to more competitive energy and related industries.
