Experimental Study of Combustion and Soot Formation of Diesel and Oxygenated Fuels

这项博士研究旨在研究柴油和含氧燃料的燃烧和碳烟形成过程。这包括对火焰稳定性、火焰剥离长度、瞬时喷射期内与火焰相关的现象和碳烟发展过程的研究。其目的是在可以控制温度和压力的加压密封室中研究这些参数。测量可以通过紫外光二极管和高速相机进行，并使用MatLab进行进一步处理。通过量化这些参数，可以实现对燃烧过程的全面了解和优化，从而推动更环保燃料的开发。这也将有助于进一步了解目前使用的燃料(柴油)的燃烧情况，进而有助于制定提高效率和减少排放的战略。

This PhD study aims to focus on the combustion and soot formation processes of diesel and oxygenated fuels. This includes the study of the flame stability, flame lift-off length, flame-related phenomena during the transient injection periods and soot development processes. The intention is to study these parameters in a pressurised chamber, for which temperature and pressure can be controlled. Measurements can be taken by means of UV photodiodes and high-speed cameras, and further processed using MATLAB. By quantifying these parameters a complete understanding and optimisation of the combustion process can be achieved, driving towards the development of more environmentally friendly fuels. This will also help further the understanding of the combustion of fuels currently in use (diesel), which in turn will help develop strategies to improve efficiency and reduce emissions.
