Characterisation of Combustion Generated Nano-particles

燃烧装置中的烟尘形成是重要的关注领域，因为已知大气烟尘造成显著的健康风险并导致长期的全球气候变化。实验和数值研究可以提供影响烟尘形成和氧化的因素的基本了解，这将有助于工程师设计燃料和发动机，减少烟尘排放到我们的大气中。 然而，烟尘的形成过程是一个复杂的化学，气溶胶动力学，流体动力学，扩散和辐射传热的相互作用。 车辆排气法规开始解决颗粒聚集数密度，而不仅仅是颗粒排放物的质量（例如，欧6法规）。 因此，需要增强的测量能力来测量常规燃料和替代燃料的颗粒聚集体数密度和结构。 所要求的仪器将为我们的研究计划提供这些重要的新功能。

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.
