在美国海军研究生院及斯坦福大学的脉冲爆震发动机 (PDE)模型上 ,应用两种新发展的二极管激光诊断技术———光吸收 /高温辐射组合测定法和多路复合可调二极管激光 (TDL)技术 ,测量了其中的温度、各燃烧产物组分等重要参数 ,并与传统方法所得结果进行对比 ,说明新方法可靠、准确 ,适合爆震燃烧流场这种特殊环境 ,测量精度更高 ,而且更加简便、快捷 At the United States Naval Graduate School and Stanford University’s pulse detonation engine (PDE) model, two newly developed diode laser diagnostic techniques, the combination of light absorption / hyperthermia radiation measurement and multiplexed tunable diode laser (TDL) ) Technology, the temperature, the composition of each combustion product and other important parameters were measured and compared with the results obtained by the traditional method. The results show that the new method is reliable and accurate, suitable for the special environment such as the knocking combustion flow field, And more simple and fast
