High-resolution imaging system for laser-based investigations of combustion energy conversion at engine-relevant conditions

由拟议设备支持的研究计划旨在为发电和运输生产具有更低NOx和颗粒物(即。碳烟气雾剂)、更高的效率和更大的燃料灵活性。特别是，我们的目标是揭开控制湍流与燃烧化学高度非线性相互作用的微观细节，并提供与近期设计改进直接相关的实际燃烧设备内部现象的新数据。在所有情况下，我们都使用一套先进的基于激光的测量技术来获取必要的数据，包括粒子图像测速、激光诱导荧光、激光诱导磷光、激光诱导白炽光、激光瑞利散射等技术。

The research program supported by the proposed equipment aims at generating innovative combustion energy-conversion devices for power generation and transportation that have lower emissions of NOx and particulate matter (viz. soot aerosol), higher efficiency, and greater fuel-flexibility. In particular, we aim both to unravel the micro-scale details controlling the highly non-linear interaction of turbulence with combustion chemistry, and to provide new data on phenomena occurring inside of actual combustion devices that are directly relevant to near-term design improvements. In all cases, we utilize an advanced suite of laser-based measurement techniques to acquire the necessary data, including techniques such as particle image velocimetry, laser induced fluorescence, laser induced phosphorescence, laser induced incandescence, laser Rayleigh scattering, and many others.
