Experimental study of jet formation during explosive dispensing of fuel
-
摘要: 通过高速录像记录3种质量不同、长径比为1.5~2.3的燃料空气炸药（FAE）装置爆炸抛撒过程的实时结果，用专门的软件对图像进行了处理。以装置上端盖为基准对解体时间进行了初步估算，由此给出了燃料初期射流量的理论估算式，结合试验结果计算了燃料的射流量。结果表明，燃料的射流量与装置的高度、装置的材质和燃料的密度等因素有关，实验研究的3种装置射流量均大于总燃料量的10%。Abstract: Three different FAE devices were tested with the aspect ration of height to diameter ranged from 1.5 to 2.3 and high-speed video was used to detect the cloud formation. Based on the digital image-processing software and referenced to the upper close end of the device, the mass formula of the jet was deduced. The results indicate that jet formation of FAE depends on device height, material and liquid density. Jet formation for each device is more 10% than its total mass.
