My research involves the development and application of optical techniques for the characterisation of reacting flows. We use light sources ranging from compact diode lasers and LEDs to high-power pulsed lasers. This experimental work is supported by data analysis and modelling to extract physically meaningful information from the measured signals.
We use these techniques to investigate the formation of soot in combustion processes. Soot (also known as black carbon) is a significant agent of climate forcing. Experimental characterisation of well-defined laboratory flames is essential to understanding the mechanism of soot formation and thus to predict and minimise its emission from combustion processes.
