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焰与壁面相互作用的基本了解，尽管火焰壁面对燃烧和污染物有重大影响，但目前这方面的研究非常有限。其目的是在高压室和光学可接近的发动机中进行迄今为止最全面的一套测量，包括关键物质和烟尘的平面成像，以及壁温的空间/时间分辨率测量。其中包括烟尘、辐射和壁面热传递的柴油喷雾火焰的首次传输概率密度函数模型是对这些模型的补充。预期的结果将极大地促进对火焰壁相互作用的了解，从而有助于开发更清洁和更高效的发动机。
