This project aims to advance the fundamental understanding of flame-wall interactions in diesel engines, which is currently very limited despite the wall's significant impact on combustion and pollutants. The aim is to perform the most comprehensive set of measurements to date in a high-pressure chamber and optically accessible engine, including planar imaging of key species and soot, and space-/time-resolved measurements of wall temperature. These are intended to be complemented by the first transported probability density function modelling of a diesel spray flame that includes soot, radiation and wall heat transfer. The expected outcomes will greatly advance understanding of flame-wall interactions, thus contributing to the development of cleaner and more efficient engines.

该项目旨在促进对柴油发动机中火壁相互作用的基本了解，尽管墙壁对燃烧和污染物的影响很大，但目前非常有限。目的是在高压室和光学上可访问的发动机（包括关键物种和烟灰的平面成像，以及壁温度的空间/时间分辨测量值）中执行最全面的测量值。这些旨在通过包括烟灰，辐射和壁热的柴油喷火火焰的第一个运输概率密度函数建模来补充。预期的结果将大大提高人们对火壁相互作用的理解，从而有助于开发更清洁，更有效的引擎。
