Microdynamic modelling and analysis of gas fluidization of particle mixtures. The project aims to develop a comprehensive understanding of the mechanisms governing the particle-fluid flow in gas fluidization of mixtures of particles of different sizes. This will be achieved through detailed analysis of the particle-particle and particle-fluid interactions on the basis of the microdynamic or particle scale results generated by the newly developed discrete simulation technique. The microscopic fin ....Microdynamic modelling and analysis of gas fluidization of particle mixtures. The project aims to develop a comprehensive understanding of the mechanisms governing the particle-fluid flow in gas fluidization of mixtures of particles of different sizes. This will be achieved through detailed analysis of the particle-particle and particle-fluid interactions on the basis of the microdynamic or particle scale results generated by the newly developed discrete simulation technique. The microscopic findings will be implemented in the macroscopic, continuum-based modelling and tested by comparing numerical and experimental results. It will significantly enhance the present capability of modelling particle-fluid flow in gas fluidization which is widely used in mineral/chemical industries.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.
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
A Fundamental Investigation into the Behaviour of Mineral Matter in Coal during Coke Formation and in Blast Furnace. Minerals in coal are present in various forms and sizes resulting in vastly different thermal behaviour. Thermal transformation of minerals in coal influences the coke properties and subsequent performance of coke in blast furnace. Earlier investigations have been based on bulk ash analysis of coals. In the current project, Computer Controlled Scanning Electron Microscopy will be ....A Fundamental Investigation into the Behaviour of Mineral Matter in Coal during Coke Formation and in Blast Furnace. Minerals in coal are present in various forms and sizes resulting in vastly different thermal behaviour. Thermal transformation of minerals in coal influences the coke properties and subsequent performance of coke in blast furnace. Earlier investigations have been based on bulk ash analysis of coals. In the current project, Computer Controlled Scanning Electron Microscopy will be used in place of bulk ash analysis for coal, coke and thermally treated coke in blast furnace simulated conditions to investigate and model the effects of minerals in coal on coke structure during coke-making and its subsequent effect on its performance in blast furnace.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
