| 摘 要： | 不起动/再起动是高超声速进气道重要的流动现象,其影响进气道的工作范围和再起动能力.针对这一问题,对一系列不同楔面转折角的混压式进气道进行了二维流场数值模拟,从流体运动稳定性的角度分析了高超声速再起动过程的流动特征,给出了以流量系数表征的不起动/再起动特性.分析了楔面转折角变化对高超声速进气道不起动/再起动特性的影响,得到了来流起动马赫数、再起动马赫数和滞环宽度随楔面转折角的变化规律.

| Abstract: | The inlet unstart/restart phenomenon is one of the most important issues to hypersonic inlets and the characteristic reflects the operation ranges and the restarting capacity of hypersonic inlets.A series of mixed-compression hypersonic inlets with different turning angles of the wedge are simulated under different freestream conditions in this paper.The reasons why the process of inlet unstart/restart is formed is discussed from the viewpoint of hydrodynamic stability.The unstart/restart characteristics of... |
