ABSTRACT CTS-9615009 The proposed project deals with an important problem in modeling radiative heat transfer. One factor that makes accurate prediction of the radiative heat fluxes in combustion systems difficult is the lack of accurate spectral properties of radiating gases. Existing property data for gases such as carbon dioxide and water vapor have an average uncertainty as large as 70%. These data were obtained more than 30 years ago. Since that time, the accuracy of detection equipment has improved tremendously. The PI proposes to use an FTIR-spectrometer and an isothermal high-temperature gas column to obtain spectral absorption data of radiating gases.

摘要CTS-9615009 建议的项目涉及辐射热建模的一个重要问题 转移 使燃烧系统中的辐射热通量的准确预测困难的一个因素是缺乏辐射气体的准确光谱特性。 二氧化碳和水蒸气等气体的现有属性数据的平均不确定性高达70%。 这些数据是30多年前获得的。 从那时起，检测设备的准确性大大提高。 PI建议使用FTIR光谱仪和等温高温气体柱来获得辐射气体的光谱吸收数据。
