气体自发光在高超声速流场显示中的应用

The Application of Gas Self Luminosity in Hypersonic Flow Field Visualization

提出了利用高焓气体自发光作为高超声速流场显示的方法，介绍了在使用高焓运行的激波风洞中，对二维模型的高超声速绕流流场使用此种方法的初步结果，可观察到二维棱形柱的尾流和马赫波的相交。结果表明此种方法不需外加光源，对于结构限制无法设置透明部件的模型，无疑是简单可行的。

This paper proposes the method of hypersonic flow field display with high enthalpy gas self luminosity and introduces some primary results employing this method in the high enthalpy shock tunnel for the hypersonic flow fields over a 2 dimension model.The results demonstrate that this method is simple and practicable without outside light source,especially for situation of light permeated limitation.
