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.

许多燃烧装置都有来自辐射换热的重要能量传递贡献。粒子辐射在许多工业应用中发挥着重要作用，如煤粉、石油和燃气炉膛、辐射燃烧器、固体推进剂火箭和燃气轮机燃烧室。不幸的是，这些颗粒的辐射特性还没有得到很好的理解，也没有得到很好的表征。这项拟议的工作旨在量化各种燃烧装置中颗粒物(烟尘)的辐射特性。这项工作的商业应用将是一种测定烟尘的就地折射率和吸收指数的装置。
