Investigation of Strategies to Improve the Efficiency of Industrial Radiators and Cooling Coils. Innovative strategies for improving in-service effectiveness of tube & plate-fin heat exchange 'coils' will be explored. Such coils are used throughout chemical process industries, diesel powered plant, vehicles and air-conditioning systems. Coil manufacture is a 'mature' industry, but design concepts have changed little since 1950.

Innovative strategies for improving in-service effectiveness of tube & plate-fin heat exchange 'coils' will be explored. Such coils are used throughout chemical process industries, diesel powered plant, vehicles and air-conditioning systems. Coil manufacture is a 'mature' industry, but design concepts have changed little since 1950. Fouling of diesel engine 'radiators' in dusty conditions and in marine environments is endemic. New design concepts evolved via Computational Fluid Dynamic analysis will be manufactured and tested in the unique heat and mass transfer wind tunnel on the University's Industry Liaison Campus. The major outcome will be a rugged design methodology with broad applicability.Read moreRead less
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
Quantification of heat release, NOx emissions and soot from high temperature gaseous flames. The ongoing importance of Australia's minerals processing sector depends on advanced combustion technology to minimise the emission of NOx and other greenhouse gases. The heat release and NOx emissions from the high temperature flames used in such processes is known to depend strongly on the presence of soot. However their optimisation and design is limited by a lack of fundamental data under relevant c ....Quantification of heat release, NOx emissions and soot from high temperature gaseous flames. The ongoing importance of Australia's minerals processing sector depends on advanced combustion technology to minimise the emission of NOx and other greenhouse gases. The heat release and NOx emissions from the high temperature flames used in such processes is known to depend strongly on the presence of soot. However their optimisation and design is limited by a lack of fundamental data under relevant conditions. To address this need, new measurements and analysis will be performed to quantify the complex relationship between turbulent mixing, soot formation, heat release and NOx emissions under high temperature conditions of both fundamental and practical significance.
