Reducing wear on rotary coal pulverisers. The aim of this project is to develop an understanding of the small-scale flows and particle breakage required to permit optimised redesign of the attrition stage of the 36 coal pulverisers at Gladstone Power Station, which, because of erosive wear, currently have a maintenance budget of $4M per year. CFD-DEM simulation of the air and particle flows will be used to determine particle flow patterns, particle-particle and particle-wall impact energies. Thi ....Reducing wear on rotary coal pulverisers. The aim of this project is to develop an understanding of the small-scale flows and particle breakage required to permit optimised redesign of the attrition stage of the 36 coal pulverisers at Gladstone Power Station, which, because of erosive wear, currently have a maintenance budget of $4M per year. CFD-DEM simulation of the air and particle flows will be used to determine particle flow patterns, particle-particle and particle-wall impact energies. This information will be input to comminution and wear models to predict pulveriser performance and wear patterns. Simulation results will be validated using measurements from scale visualisation and working models.Read moreRead less

Wet granule mechanics and their influence on agglomeration behaviour and granulation processes. Granulation is a widely-used particle size enlargement process performed by spraying a liquid binder onto an agitated powder mass. It is currently impossible to quantitatively predict granule growth behaviour in terms of the fundamental properties of the particles and binder. This project will measure and model the deformation of granules and the strength of bonds formed between them and use this info ....Wet granule mechanics and their influence on agglomeration behaviour and granulation processes. Granulation is a widely-used particle size enlargement process performed by spraying a liquid binder onto an agitated powder mass. It is currently impossible to quantitatively predict granule growth behaviour in terms of the fundamental properties of the particles and binder. This project will measure and model the deformation of granules and the strength of bonds formed between them and use this information to predict their growth behaviour. Special attention will be given to the effects of strain-rate and particle morphology in granulation mechanics. Improvements in granulation technology will be of great benefit to food, pharmaceutical, agricultural, explosives and mining industries and opens the way to 'designer granulation' for special purposes.Read moreRead less
Simulation studies of stick and slip at the solid-liquid boundary. Successful practical application of computational rheology to polymer processing, to adhesion and to the understanding of lubrication at very high shear rates, among other problems, needs both an adequate description of the fluid - a constitutive equation - and the prescription of proper boundary conditions.The constitutive model problem has been extensively studied, and this proposal seeks to address the question of proper bound ....Simulation studies of stick and slip at the solid-liquid boundary. Successful practical application of computational rheology to polymer processing, to adhesion and to the understanding of lubrication at very high shear rates, among other problems, needs both an adequate description of the fluid - a constitutive equation - and the prescription of proper boundary conditions.The constitutive model problem has been extensively studied, and this proposal seeks to address the question of proper boundary conditions for viscoelastic flow at interfaces between a flowing fluid and a solid surface. This vital area has not been thoroughly studied theoretically and computationally, and we seek to clarify the mechanisms by using molecular dynamics.Read moreRead less

This project concerns curved structural members, such as bridge beams, that are subjected to dynamic excitation and to concrete shrinkage and creep. Hitherto, unified formulations for the structural behaviour of these members have not been properly developed. The proposal seeks to build on a previous ARC DP of the investigator that produces significant results for static loading, by developing a sophisticated methodology to handle non-static dynamic loading and for shrinkage and creep. It will develop advanced mathematical tools to enable the safe and efficient design of a multiplicity of structures that is of benefit to on and offshore Australian technology.Read moreRead less

Nano particulates are the basis for many new technologies, including coatings in the electronics industry, composite materials and medical and pharmaceutical applications. Worldwide industrial competition is increasingly determined by our capacity to handle such highly cohesive materials, and to exploit their novel physical, chemical and mechanical characteristics. Devising handling mechanisms and understanding nano particulate flows depends on formulating accurate mathematical models which reflect the correct underlying physics. This APF proposal will utilise advanced continuum mechanics to develop the correct underlying conceptual ideas to resolve fundamental nanomechanical particulate flows, which will lead to the next generation of engineering tools.
