| 摘 要： | 激光多普勒测速仪的出现使紊流速度场的准确测量变成了现实，紊流火焰温度分布和浓度分布等标量的测试研究成了国内外燃烧研究工作者极为感兴趣的课题。阐述作者在德国宇航院燃烧物理化学研究所采用激光自发喇曼散射法（ＬａｓｅｒＳｐｏｎｔａｎｅｏｕｓＲａｍａｎＳｃａｔｔｅｒｉｎｇ）所进行的紊流扩散火焰实验研究工作，其测试结果与采用紊流雷诺应力模型的数值模拟结果十分吻合

| Abstract: | Since the appearance of Laser Doppler Anemometer,the accurate measurement for the turbulent velocity has become reality. The determination of the scalar properties, for example, temperature and species concentration has received increased attention in studying turbulent combustion. Results from temperature and species concentration of Laser Spontaneous Raman Scattering measurements in an H 2/N 2/air turbulent diffusion flame are reported. A comparison of the measurements with Reynolds stress model prediction is given. The agreement is very good. |
