Fracture propagation through fragmented solids. This project investigates fracture propagation in heavily fractured (fragmented) solids such as rock masses, ice covers, fractured coatings, mortar-free structures. It introduces new ideas and methods and has potential to result in a breakthrough science to achieve better understanding of the fundamental processes of fracturing fragmented materials that will advance knowledge and develop technological innovations.

This project investigates fracture propagation in heavily fractured (fragmented) solids such as rock masses, ice covers, fractured coatings, mortar-free structures. It introduces new ideas and methods and has potential to result in a breakthrough science to achieve better understanding of the fundamental processes of fracturing fragmented materials that will advance knowledge and develop technological innovations. A particular outcome of the project will be in developing tools for designing new materials with enhanced failure resistance. Another application is in Resource Engineering and Earth and Planetary Science; the project will contribute to understanding of fracture propagation in the Earth's (and generally, planetary) crust.Read moreRead less
A Paradigm Shift in the Hydrodynamics of Ion Flotation. Ion flotation has delivered remarkable separations via high selectivity, recovery and concentration upgrade. Yet, the technology has not provided solutions that are economically viable. This new project, however, aims to deliver the paradigm shift required in the flotation hydrodynamics to finally permit ion flotation to be applied to a broad range of industrial problems. Specifically, the aim is to increase extraction rates by more than an ....A Paradigm Shift in the Hydrodynamics of Ion Flotation. Ion flotation has delivered remarkable separations via high selectivity, recovery and concentration upgrade. Yet, the technology has not provided solutions that are economically viable. This new project, however, aims to deliver the paradigm shift required in the flotation hydrodynamics to finally permit ion flotation to be applied to a broad range of industrial problems. Specifically, the aim is to increase extraction rates by more than an order of magnitude by dramatically increasing bubble-liquid segregation rates, and bubble-surface fluxes. In turn the project is expected to develop a new line of solutions to industrial problems in hydrometallurgy for recovering precious metals and for solving toxic environmental problems.Read moreRead less
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
Variational multiscale modelling of granular materials. Granular materials play an important role in a wide-range of problems related to physical infrastructure. These include landslides and similar catastrophic events often leading to loss of life and property. This project will aim to develop new methods for adequate simulation of granular flows to allow formulation of efficient risk mitigation strategies.
Feasibility of biological hydrogen production from biomass wastes using activate sludge microorganisms. This study will focus on biological hydrogen production from biomass wastes, not only because hydrogen is a clean and high efficient energy, but also because it can be a process for waste treatment. The research is aimed at examining the feasibility of biological hydrogen production from an organic waste stream by hydrogen producing bacteria isolated and enriched from pretreated digested activ ....Feasibility of biological hydrogen production from biomass wastes using activate sludge microorganisms. This study will focus on biological hydrogen production from biomass wastes, not only because hydrogen is a clean and high efficient energy, but also because it can be a process for waste treatment. The research is aimed at examining the feasibility of biological hydrogen production from an organic waste stream by hydrogen producing bacteria isolated and enriched from pretreated digested activated sludge. The overall goal is to get better understanding of the biochemical mechanisms, metabolic pathways effecting on the intermediate and end-products, leading to high hydrogen productivity and yield.Read moreRead less

Summary
Heat flow in granular media under extreme loading conditions. Heat flow in granular media is critical in geoscience and engineering, from shear heating in earthquake faults to failures of granular heat exchangers. These problems involve complex conditions which this project will quantify in relation to the emerging phenomena of grain plasticity and melting and thermal pressurisation.
