説明
Spectroscopic measurements were made of a shock layer generated by a flat-head body in high-enthalpy air and nitrogen plasma flows of NAL 750kW arc-jet wind tunnel. In the wavelength region of 350nm to 450nm, N_2^+ 1- band was predominant in the nitrogen jets and the N_2^+ 1- and CN violet bands in the air jets. These bands were analyzed in detail by using synthetic spectra calculated theoretically. Temperature determination of the shock layer was tried by applying a spectral matching method to these band systems. In case of the nitrogen plasma jet, axial temperature distribution across the shock layer was measured and compared with the flow calculation based upon the modified fully-merged shock layer theory. It was found that the rotational temperature in the shock layer for both the arc jets was about 7000K, and the tempeature of a free stream in the nitrogen plasma jets was much higher than that expected.
