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

辐射传热对许多燃烧装置的能量传递都有重要的贡献。粒子辐射在许多工业应用中起着重要的作用，如煤粉、燃油和燃气炉、辐射燃烧器、固体推进剂火箭和燃气轮机燃烧器。不幸的是，这些粒子的辐射特性并没有被很好地理解，也没有被很好地表征。这项拟议的工作旨在量化颗粒（烟灰）在各种各样的燃烧装置的辐射特性。这项工作的商业应用将是测定烟灰的原位折射率和吸收指数的装置。

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.
