摘要： 为研究航空煤油全氟己酮燃烧抑制过程中OH自由基的变化规律，设计带有光学开窗的杯式燃烧器，以OH-PLIF技术为测量手段，利用2种不同波长的“差分法”测量方法克服了航空煤油燃烧场中碳烟、煤油及燃烧裂解大分子化合物对OH自由基荧光信号的干扰问题，获得了12组不同全氟己酮体积分数条件下的OH基分布特征图，对研究全氟己酮的抑制机理具有重要的参考意义，为理论模型的建立提供了基础数据。试验结果表明：对于OH基分布的垂直高度值H，在全氟己酮处于较低体积分数时（＜3.91%），H值缓慢增长，但随着体积分数的持续增加，H值会快速下降，随后逐渐趋于平缓；而对于OH基分布带的厚度值D和OH分布区域的占比S，随着全氟己酮体积分数的增加，两者呈现明显下降趋势。

Abstract: In order to make a profound study on the change rule of OH which was restrained by C6F12O in combustion process of aviation kerosene, a cup burner with optical windows was designed. Based on OH-PLIF (planar laser?induced fluorescence) technology, the "difference method" measurement which was used two different wavelengths, solved the problem that was caused by soot, kerosene and combustion cracking macromolecular compounds in combustion field of aviation kerosene. The OH distribution characteristic maps of twelve experimental conditions were obtained. The maps had important reference significance for studying the inhibition mechanism of  C6F12O, and they also provided basic dates for establishing theoreti-cal model of the inhibition mechanism. The experimental results showed that parameter H which meant the vertical height of OH distribution was stretched slowly if  C6F12O was low volume fraction (<3.91%). However, parameter H would decline rapidly then gradually gently if the concentration  C6F12Owas rising continuously. In addition, parameter D which meant the thickness of OH distribution zone and parameter S which meant the proportion of OH distribution area were showing obvious downward trend if the concentration of  C6F12Owas rising continuously.
