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.

该研究项目将继续并完成对高温燃烧气体，特别是二氧化碳和水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性为正/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在任意燃烧气体/颗粒环境中进行辐射传热计算的能力，包括燃烧室和炉膛、火焰和推进系统，从而改善这些系统的性能和设计。
