摘要
采用纹影摄象、激光多普勒测速系统和气体色谱仪等测试方法,对内燃机等各种热力机械中常见的横向气流场中垂直喷射紊流扩散燃烧现象进行了研究,提出了描述火焰轨迹的经验公式,得出了与火焰喷流轴线垂直的横截面上的流速、温度及气体浓度分布均呈现肝脏形的结论。
By using Schlieren method,LDV and gas chromatography,a study was made of the turbulent diffusion flame jetted vertically in cross gas flow frequently seen in ICE and other heat engines.This paper givesthe empirical equation depicting the flame locus,with the conclusionthat distributions of the flow velocity,temperature and gas concentra-tions in the cross section normal to the flame jet axis take the shape ofthe liver.
