Heat-resisting iron-nickel base alloys in challenging new applications: oxygen permeabilities and resistance to internal oxidation. There is a pressing need to develop heat resisting alloys which can function adequately in higher operating temperatures and gas mixtures rich in carbon and hydrogen to be handled in advanced technologies for power generation. The expected outcomes of this project will provide the basis for design/selection of these more corrosion-resistant alloys.
Reducing gas and ash corrosion in advanced power generation. Advanced power generation using new coal combustion technologies increases energy efficiency and makes carbon dioxide capture possible, but increases the corrosion problems. This project aims to determine the corrosion behaviour of chromia-scale forming iron- and nickel-base alloys in the presence of deposits (coal ashes and salts) under carbon dioxide rich gas atmospheres. The increased understanding of alloy behaviour in hot corrosiv ....Reducing gas and ash corrosion in advanced power generation. Advanced power generation using new coal combustion technologies increases energy efficiency and makes carbon dioxide capture possible, but increases the corrosion problems. This project aims to determine the corrosion behaviour of chromia-scale forming iron- and nickel-base alloys in the presence of deposits (coal ashes and salts) under carbon dioxide rich gas atmospheres. The increased understanding of alloy behaviour in hot corrosive ashes and gases, will permit more effective materials design and selection leading to more efficient and economic technologies for reliable and low cost carbon capture in energy production, waste-energy conversion and related industries.Read moreRead less
High temperature corrosion induced by multiple secondary oxidants . Heat resisting chromia-forming alloys passivate successfully in clean, dry air at temperatures up to about 950°C. However, this performance is degraded by secondary oxidants (carbon, sulphur, chlorine, water vapour), leading to corrosion failure in important industries. The project aims to investigate the effect of these secondary oxidants on corrosion behaviour of chromia-forming alloys, to identify interactions between multipl ....High temperature corrosion induced by multiple secondary oxidants . Heat resisting chromia-forming alloys passivate successfully in clean, dry air at temperatures up to about 950°C. However, this performance is degraded by secondary oxidants (carbon, sulphur, chlorine, water vapour), leading to corrosion failure in important industries. The project aims to investigate the effect of these secondary oxidants on corrosion behaviour of chromia-forming alloys, to identify interactions between multiple oxidants within the scale, to establish the mechanisms of oxide scale penetration by foreign species, and to evaluate scales on different alloy types. The results will provide a basis for improved design/selection of heat resisting chromia-forming alloys, key to power generation industries.Read moreRead less

Engineered functional metal silica membranes for hydrogen processing. This project focuses on hydrogen processing technologies for the petrochemical, agricultural and coal/energy industries. These sectors employ 110,000 people with annual combined revenues of $80 billion. Advanced technologies are vital for the competitiveness of the Australian economy, and to sustain Australia's social stability and economic growth.
Understanding rough-wall flows and turbulent mixing for improved models. In the absence of a reliable predictive capability for turbulent heat transfer, design engineers are currently forced to incorporate safety margins into their calculations to compensate for aero-thermal loading uncertainty, which ultimately limits the opportunities for high-efficiency designs. This project employs high-fidelity simulations and experiments of real-world heat transfer problems, as identified by our partner or ....Understanding rough-wall flows and turbulent mixing for improved models. In the absence of a reliable predictive capability for turbulent heat transfer, design engineers are currently forced to incorporate safety margins into their calculations to compensate for aero-thermal loading uncertainty, which ultimately limits the opportunities for high-efficiency designs. This project employs high-fidelity simulations and experiments of real-world heat transfer problems, as identified by our partner organisation, MHI, an industry leader, combined with a novel data-driven model development framework. Outcomes will be a fundamental advance in our predictive capability and understanding of turbulent heat transfer, which in turn will permit more reliable, efficient and durable designs for energy generation.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.
Towards an event based model of combustion generated sound. This proposal will develop new tools for predicting combustion generated sound. Since combustion noise often limits system performance, these new tools could be used to significantly reduce emissions of greenhouse gases and other pollutants from power generation and transportation.
