摘要
为了对羽流激波中金属光谱特性进行研究 ,用煤油 氧火焰气体模拟煤油 氧发动机的羽流 ,以二茂铁溶于煤油模拟发动机材料铁的磨损 ,给出不同混合比下铁在火焰中辐射光谱的实验与仿真结果。实验光谱数据随铁的浓度不同而变化 ,理论光谱与实验结果吻合较好 ,验证了羽流中金属原子辐射光谱的仿真程序。
In order to study atomic spectroscopy in the diamond of the plume, a kerosene-oxygen flame on a lamp was used to simulate the plume of the liquid oxygen/ kerosene rocket engine, the ferrocene dissolved in the kerosene was used to simulate the Fe erosion of the engine The different experimental spectra of iron in different concentration were obtained respectively, the simulation results of the experimental ones were also presented The experimental results vary with the concentration; the simulation result fits satisfactorily for the measured one, which validates the simulation code of atomic radiation spectrum in the plume The qualitative study lays experimental and theoretical foundation for the research of engine diagnosis based on plume spectral analysis
