Characterisation of Combustion Generated Nano-particles

燃烧装置中的煤烟形成是一个重要的研究领域，因为众所周知，大气中的煤烟会造成重大的健康风险，并导致长期的全球气候变化。实验和数值研究可以提供对影响烟灰形成和氧化的因素的基本理解，这将有助于工程师设计向大气中排放较少烟灰的燃料和发动机。然而，烟灰的形成过程是化学、气溶胶动力学、流体动力学、扩散和辐射传热的复杂相互作用。汽车尾气排放法规开始解决颗粒总数密度问题，而不仅仅是颗粒排放的质量问题（例如欧6法规）。因此，需要增强测量能力来测量常规和替代燃料的粒子聚集数、密度和结构。所要求的仪器将为我们的研究项目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.
