Narrow-Banded Radiative Properties and Heat Transfer Models for High-Temperature Combustion Gases

这项研究计划将继续并完成对高温燃烧气体，特别是CO2和H2O的辐射特性的实验研究。这些气体的现有性质数据的平均不确定度为正负30%，在某些情况下误差可能高达70%。PI将使用独特的等温高温气柱和FTIR光谱仪，以确保比以前的高温测量更好的光谱分辨率。潜在的影响是显著提高了在任意燃烧气体/颗粒环境(包括燃烧室和炉子、火灾和推进系统)中进行辐射换热计算的能力，从而改进了这些系统的性能和设计。

This research program will continue and complete an experimental investigation of the radiative properties of high temperature combustion gases, particularly CO2 and H2O. Existing property data for these gases have an average uncertainty of plus/minus 30% and may be in error in some cases by as much as 70%. The PI will use a unique isothermal high-temperature gas column and an FTIR spectrometer to ensure better spectral resolution than previous high temperature measurements. The potential impact is a significantly improved capability to make radiative heat transfer calculations in arbitrary combustion gas/particulate environments, including combustion chambers and furnaces, fires, and propulsion systems, and therefore improve the performance and design of these systems.
