The Formation and Emission of Soot Nanoparticles from Turbulent Flames

该项目旨在开发实验和数值方法，使设计人员能够控制燃烧室碳烟纳米颗粒的形成和排放。污染我们大气层的超细颗粒物来自燃烧源，现已证实对健康构成严重威胁。因此，新法规将对发动机排放的颗粒物数量进行严格限制。要满足这些规定，需要对控制湍流火焰中烟尘演变的机制有一个尚未得到的了解。本项目计划使用激光诊断方法来构建实验框架，以促进模型开发。由此产生的预测能力将有助于一个平台，使工程师能够优化燃烧室设计。

This project aims to develop experimental and numerical approaches that will enable designers to control the formation and emission of soot nanoparticles from combustors. Ultrafine particles polluting our atmosphere originate from combustion sources and are now confirmed to pose serious health risks. As a result, new regulations will impose strict limits on the number of particles that can be emitted from engines. Satisfying such regulations requires a yet unavailable understanding of the mechanisms that control the evolution of soot in turbulent flames. This project plans to use laser diagnostic methods to construct the experimental framework that will facilitate model development. The resulting predictive capabilities would contribute to a platform that enables engineers to optimise combustor designs.
