Gassing Mechanism and Stability of Foamed Explosive Emulsions. Mining of minerals such as coal involves crushing the surrounding rock strata, or the mineral ore itself, with emulsion explosives. One of the most important properties determining suitability of an emulsion explosive to a particular mining operation is its velocity of detonation, which can be adjusted by varying the number and size of air bubbles distributed in the emulsion matrix. The present project aims to develop new ways of g ....Gassing Mechanism and Stability of Foamed Explosive Emulsions. Mining of minerals such as coal involves crushing the surrounding rock strata, or the mineral ore itself, with emulsion explosives. One of the most important properties determining suitability of an emulsion explosive to a particular mining operation is its velocity of detonation, which can be adjusted by varying the number and size of air bubbles distributed in the emulsion matrix. The present project aims to develop new ways of generating air bubbles, to gain fundamental understanding of the foaming mechanism in currently used gassing techniques, and to invent ways to stabilise large bubbles within the emulsion. The project will provide scientific underpinning for the development of a new range of emulsion explosives manufactured by Orica for Australian and international markets, maintaining the Orica's position as a leader in the field of emulsion explosives.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

Summary
Testing facilities for clean energy transformation technologies. As the world approaches peak oil production, the use of gasification to convert solid fuels to hydrogen and liquid fuels provides a low carbon footprint approach to the cleaner transformation of energy. This testing facility for clean energy transformation technologies will enhance the competitiveness of Australian science and engineering, contributing to the development of new technologies.
The separation of carbon dioxide from industrial sources using nanoporous carbon. Carbon nanotubes and nanoporous carbon membranes offer the possibility of low cost energy efficient separations of gas mixtures. Possible applications include the purification of greenhouse gases for sequestration and the purification of hydrogen from reformer gas for use in a hydrogen energy economy.

Carbon nanotubes and nanoporous carbon membranes offer the possibility of low cost energy efficient separations of gas mixtures. Possible applications include the purification of greenhouse gases for sequestration and the purification of hydrogen from reformer gas for use in a hydrogen energy economy. The proposed project involves the development of mathematical models and computer simulations to understand and optimise the nanoporous structure for different gas separations, and experimental research to produce the carbon nanoporous materials and determine their effectiveness of gas separation.Read moreRead less
