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
Study of hydrocarbon flames under heat and gas recirculation conditions. This project aims to study gaseous flames under heat and gas recirculation conditions. This technology has been proven to reduce fuel consumption, improve thermal efficiency and substantially reduce nitric oxides emission. The effect of mixing, turbulence and temperature on the structure and stability of these flames will be investigated. The project combines experimental and computational research applied to a laboratory s ....Study of hydrocarbon flames under heat and gas recirculation conditions. This project aims to study gaseous flames under heat and gas recirculation conditions. This technology has been proven to reduce fuel consumption, improve thermal efficiency and substantially reduce nitric oxides emission. The effect of mixing, turbulence and temperature on the structure and stability of these flames will be investigated. The project combines experimental and computational research applied to a laboratory scale burner and a small scale furnace. The main objectives are to better understand the chemical pathways in low temperature hydrocarbon flames under heat and gas recirculation conditions and to understand the effect of mixing and turbulence on the flame structure and pollutants emission.Read moreRead less
Gas phase studies of reactive organic radicals: a novel approach using mass spectrometry. Radical reactions play a crucial role in a range of important chemistries, ranging from the formation of photochemical smog to the accumulation of pathogens in the ageing body. Despite their importance, the reactions of many radicals are poorly understood because of current experimental limitations. In this project we propose to develop two new and broadly applicable techniques for probing radical chemistry ....Gas phase studies of reactive organic radicals: a novel approach using mass spectrometry. Radical reactions play a crucial role in a range of important chemistries, ranging from the formation of photochemical smog to the accumulation of pathogens in the ageing body. Despite their importance, the reactions of many radicals are poorly understood because of current experimental limitations. In this project we propose to develop two new and broadly applicable techniques for probing radical chemistry in the gas phase via novel applications of mass spectrometry. Combined with quantum chemical calculations and state-of-the-art thermodynamic measurements these methods will provide a comprehensive understanding of the reactivity of key organic radicals.Read moreRead less
Anomalous isotope effects in atmospheric ozone and carbon dioxide. The anomalous isotopic composition of atmospheric ozone, which has been a puzzle for over twenty years, will be investigated by laboratory and atmospheric measurements. An understanding of the source of this anomaly and its effect on the isotopic composition of other trace atmospheric gases, especially CO2, would provide unique opportunities for constraining the tropospheric and stratospheric ozone budgets and determining the his ....Anomalous isotope effects in atmospheric ozone and carbon dioxide. The anomalous isotopic composition of atmospheric ozone, which has been a puzzle for over twenty years, will be investigated by laboratory and atmospheric measurements. An understanding of the source of this anomaly and its effect on the isotopic composition of other trace atmospheric gases, especially CO2, would provide unique opportunities for constraining the tropospheric and stratospheric ozone budgets and determining the history of a particular air mass. The method of detection will be high resolution FTIR spectroscopy which, in contrast to traditional mass-spectrometric methods, provides information about the position of the heavy atom in an enriched ozone molecule and requires no sample preparation.Read moreRead less
