摘要
基于气体分子辐射吸收指数宽带模型,分析了火焰温度和组分浓度的诊断原理和计算方法;建立了红外光谱诊断系统,并进行了实验研究,结果表明诊断精度较高.
Based on the theory of exponential wide band model of radiation absorption of gas molecules, the principle formulas of infrared spectroscopy diagnosis for flame temperature and composition concentration were deduced and a kind of practical calculating method was given. An infrared spectroscopy diagnosis system was established, and the experimental research was carried out with the system. The results show that the accuracy is relatively high, Thus, the aim to measure the flame temperature and composition concentration synchronously has been achieved.
