查询词典 supersonic speed

In addition to measurements of conventional dynamic parameters o n a model surface,an optical observation method was employed,which directly reco rded self-luminosity of high temperature gas induced by a two-dimensional mode l in high enthalpy flow and combustion radiation.Hypersonic flow fields passing over a sharp strut including fuel injection were displayed and recorded with a high-speed CCD camera.A phenomenon of supersonic diffusive combustion under fre e boundary condition was observed.

实验除测量常规流场参数和模型表面的动态参数外，主要使用二维实验模型，利用高温气体的自发光和燃烧伴随的发光现象，采用高速摄影技术来观测燃烧现象，记录到高焓流场中叠加燃料喷射和燃烧的流场，观察到自由边界条件下扩散控制的超声速燃烧现象。
