放電場の温度測定に向けたＮ2、Ｎ2+理論スペクトル計算

抄録

Temperature measurement of the DC discharged field is crucial to understand the fluid dynamic effect such as shock wave modulation due to the interaction with the discharged field. For the temperature determination, spectrum matching method based on the emission spectrum is promising as one of the non-intrusive methods. For using the spectrum matching method, database of the theoretical spectrum of chemical species is required. For the method, our research group has developed a theoretical spectrum calculation code for molecular nitrogen and ion of the molecular nitrogen. Then, based on the code, we have constructed the database. Especially for the molecular nitrogen spectrum, the presently developed code was verified by the comparison with the published results. And we obtained the fairly good agreement between them. Hereafter, for the application of the spectrum matching method to the temperature determination from the experimental spectroscopic data, the fitting code should be developed.
