Despite limited resources, the world will continue to rely heavily on fossil fuels to satisfy the growing energy requirements. There is a pressing need, therefore, for cleaner, more efficient combustion not only to conserve energy but also to reduce environmental emissions of pollutants. This project tackles several major areas of turbulent combustion covering premixed and nonpremixed flames of gaseous and liquid fuels. Each project involves complex calculations and validation with measurements obtained using advanced laser diagnostic methods. This is a major research program leading to advanced numerical methods which will eventually be implemented in numerical tools to optimise combustor designs.Read moreRead less

Stability, transition and heat transfer in thermally coupled natural convection boundary layers. Thermally coupled natural convection systems occur when a conducting vertical wall separates two fluids at different temperatures. Such configurations occur, for example, at a window separating the interior of a room from the outside or when a container of fluid is placed in a refrigerator.

Thermally coupled natural convection systems occur when a conducting vertical wall separates two fluids at different temperatures. Such configurations occur, for example, at a window separating the interior of a room from the outside or when a container of fluid is placed in a refrigerator. Improved building heating/cooling and ventilation, and more efficient refrigeration systems, require a thorough understanding and predictive capability for these flows. This project will develop experimental, numerical and analytic tools to predict these flows and provide simple scaling relations for bulk flow parameters such as the heat transfer across the wall, which will be of immediate use in the associated industries.Read moreRead less
