| 摘 要： | 介绍了用单脉冲BOXCARS技术测量含铝固体燃剂燃烧场的温度及氮气的浓度。分析了激光光束质量对CARS信号强度的影响,给出了在燃烧场中取得的单脉冲CARS光谱,并进行了理论拟合,得到了燃烧场的温度及组份浓度数据。在燃烧场中心高5mm处温度值约为2550K,氮气浓度平均为25.5%。测量了燃烧场中不同高度处CARS光谱,给出了燃烧场温度、氮气浓度随高度变化的曲线,对结果进行了分析。

| Abstract: | The temperature and concentration distribution in the aluminiferous solid fuel combustion are measured by BOXCARS with single laser pulse. The data are acquired at high temporal and spatial resolution. Results indicate that temperature is as high as 2550K at 5mm height above fuel surface and concentration of N2 is about 25.5% in the combustion. Connection of CARS signal intensity and laser beam quality is analyzed. The laser beam is optimized for enhance the signal intensity. |
