氮气，5%氩气），对于散装煤，范围为6.5 MJ/kg至18.4 MJ/kg。流动可视化图像揭示了大尺度不稳定流动结构的存在，并且指示对于低于约11 MJ/kg的散装重油，超过70%的核心流的一氧化氮荧光信号，但是对于高于约16 MJ/kg的散装重油，超过小于10%的核心流的一氧化氮荧光信号。使用分子标记测速法（MTV）进行轴向测速。沿着中心线测得的轴向速度约为3 km/s。通过扫描窄带激光的波长并分析所产生的多普勒频移来进行径向速度测量。径向速度为±0.5km/s。
nitrogen, 5% argon), for bulk enthalpies ranging from 6.5 MJ/kg to 18.4 MJ/kg. Flow visualization images reveal the presence of large scale unsteady flow structures, and indicate nitric oxide fluorescence signal over more than 70% of the core flow for bulk enthalpies below about 11 MJ/kg, but over less than 10% of the core flow for bulk enthalpies above about 16 MJ/kg. Axial velocimetry was performed using molecular tagging velocimetry (MTV). Axial velocities of about 3 km/s were measured along the centerline. Radial velocimetry was performed by scanning the wavelength of the narrowband laser and analyzing the resulting Doppler shift. Radial velocities of ±0.5km/s were measured.
