摘要
利用光学多道分析仪,在JF-10氢氧爆轰驱动高焓激波风洞上测量了二维钝体驻点的发射光谱.实验结果表明,在200～280nm的波长范围内,辐射主要来自NO的γ系,同时还分辨出了OH的A-X跃迁、N2+的B-X跃迁和烧蚀金属的原子线辐射.
Non-intrusive measurement has been made to investigate emission spectra from shock layer flow in JF-10 shock tunnel, which is first driven by hydrogen oxygen detonation driver. The optical multi-channel analyzer is employed to obtain radiance for 2-d hypersonic blunt body flow. The results show the main Emission spectra at wavelength range from 200-280nm is mainly come from NO γ system (A2∑→X2∏ transition). Strong emission from OH A-X transition, N2+(1-) B-X transition and metal particles were also observed.
