【摘要】 本文主要介绍了爆轰波驱动技术在激波风洞实验方面的应用。首先,JF-10高焓激波风洞,经过努力成功地实现带扩容腔的变截面氢氧爆轰方式运行。对该风洞状态调试结果表明,爆轰波能量利用更为合理,气流特性获得明显的改进。报告还具体描述了高温气体流动中壁面催化性能对热流影响的对比实验的方法和模拟试验的初步结果。文章最后说明爆轰波驱动技术在再入大气层气动物理的模拟试验方面有广阔的应用前景。更多还原

【Abstract】 This paper is mainly concerned with the oxygen hydrogen detonation driving technique, which is used in JF-10 shock tunnel to explore the high temperature real gas effects on heat transfer. The experiments proved that the forward detonation driven shock wind tunnel with expanding cavity can solve the attenuation problem of incident shock and improve the test flow condition. This paper also describes the test method of measuring catalyst effects on heat transfer. The results show that detonation driven shock tunnel technique is useful for experimental research of reentry problems.更多还原
