本文对膜片处起爆的氢氧爆轰驱动的概念作了简要描述。爆轰波在管端盖板上的反射压力峰值高出初始压力200多倍,在高起始压力条件下产生的如此高的反射峰压对设备安全极为不利。串接在驱动段末端的卸爆段既能消除高的反射峰压,又能延长有效驱动时间。实验结果还表明:爆轰波后气流的定常性和重复性品质优良。用爆轰驱动来产生高焓(具有高压)试验气流是一种高性能且节省费用的新方法。还可用来获得高雷诺数高马赫数试验气流。爆轰驱动具有广阔的应用前景。
In this paper, the concept of oxyhydrogen detonation driven at the diaphragm is briefly described. The peak pressure of detonation wave reflected in the end cap is more than 200 times higher than the initial pressure. Such high peak pressure under high initial pressure conditions is extremely detrimental to the safety of the equipment. The discharging section concatenated at the end of the driving section can not only eliminate the high reflection peak pressure but also prolong the effective driving time. The experimental results also show that the detonation wave flow after the regularity and repeatability of good quality. Detonation-driven production of high-enthalpy (high-pressure) test streams is a new, high-performance and cost-effective method. It can also be used to obtain high Mach numbers for high Reynolds numbers. Detonation drive has broad application prospects.
