Characterisation of Combustion Generated Nano-particles

Soot formation in combustion devices is an important area of interest, as atmospheric soot is known to pose significant health risks and contribute to long term global climate change. Experimental and numerical studies can provide a fundamental understanding of the factors affecting soot formation and oxidation, which would assist engineers in designing fuels and engines that emit less soot into our atmosphere. However soot formation processes are a complex interaction of chemistry, aerosol dynamics, fluid dynamics, diffusion and radiation heat transfer. Vehicle exhaust regulations are starting to address the particle aggregate number density rather than just the mass of particle emissions (e.g. Euro 6 regulations). Thus enhanced measurements capabilities are need to measure particle aggregate number density and structure of conventional and alternative fuels. The requested instrument will provide these important new capabilities to our research programs.
