摘要
本文介绍了日本国立日本大学(Universiti Tenaga nationalunien)短持续时间高速激波通道性能评价的实验过程。实验工作包括压力、峰值压力、冲击强度和冲击速度的测量。介绍了该设备的物理描述和运行原理。通过安装在设施末端的三个站点的快速响应压力传感器,可以捕获流动过程的压力历史。测量使用了两种不同的驱动/驱动气体组合。第一个是Air-Air,第二个是Helium-Air。对两种组合的结果进行了比较分析。结果表明,气体组合对装置的性能有很大影响。研究结果为膜片破裂后得到的上述参数提供了很好的估计,也有助于更好地理解影响设施性能的参数。
Experimental performance evaluation of short duration high speed flow shock tunnel
This paper describes the experimental procedure to evaluate the performance of short duration high speed flow shock tunnel located at the Universiti Tenaga Nasional “UNITEN”. The experimental work includes measurements of pressure, peak pressure, shock strength and shock speed. Physical description of the facility along with the principle of operation is presented. The pressure history of flow process was captured using fast response pressure transducer mounted at three stations located at the end of the facility. The measurements were performed using two different driver/driven gas combination. The first one is Air-Air while the second one was Helium-Air. The results of two combinations were compared and analyzed. The results show that the facility's performance is highly influenced the gas combination. The results provide very good estimate for the above mentioned parameters obtained after diaphragm rupture and also provide better understanding of the parameters that affect the performance of the facility.
