In-Situ Determination of Refractive and Absorptive Indices of Soot Particles

许多燃烧装置具有重要的能量传递 辐射传热的贡献。 粒子辐射 在许多工业应用中起着重要作用， 煤粉、燃油和燃气炉，辐射燃烧器， 固体推进剂火箭和燃气涡轮机燃烧室。 不幸的是，微粒的辐射特性 没有被很好地理解也没有被很好地描述。 这项拟议的工作 试图量化颗粒（煤烟）的辐射特性 在各种各样的燃烧装置中。 商业 这项工作的应用将是一种设备，以确定 烟灰的原位折射率和吸收率。

Many combustion devices have an important energy transfer contribution from radiation heat transfer. Particle radiation plays a significant role in many industrial applications such as pulverized-coal, oil, and gas-fired furnaces, radiative burners, solid propellant rockets, and gas turbine combustors. Unfortunately, the radiative properties of the particulates are not well-understood nor well-characterized. This proposed work seeks to quanitfy the radiative properties of particulate (soot) in a wide variety of combustion devices. The commercial application of this work would be a device to determine the in-situ refractive and absorptive indices of soot.
