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
Laser Diagnostics of Soot Formation in Precessing Jet Flames. In many practical combustion systems (e.g., boiler furnaces and rotary kilns), flame radiation is the major contributor to the required heat transfer. Soot formation is a means of enhancing flame radiation provided the soot is completely oxidised within the flame so that there are no soot emissions. The enhanced flame radiation can have a significant economic and environmental impact on plant operation (changes to the parameters tha ....Laser Diagnostics of Soot Formation in Precessing Jet Flames. In many practical combustion systems (e.g., boiler furnaces and rotary kilns), flame radiation is the major contributor to the required heat transfer. Soot formation is a means of enhancing flame radiation provided the soot is completely oxidised within the flame so that there are no soot emissions. The enhanced flame radiation can have a significant economic and environmental impact on plant operation (changes to the parameters that influence soot formation can also influence NOx and greenhouse gas emissions). The objectives of this project are to identify and quantify the operating parameters that influence soot formation and destruction in such flames.Read moreRead less
