摘要近年来，随着人类对燃油的需求量日益增大，各种类型的油类火灾、爆炸事故也频频发生。油类事故一旦发生，难以控制，会造成巨大的人员伤亡与财产损失。为探究激波作用下的油料抛洒雾化情况及其遇到点火源时的燃爆性能，我们通过自行设计实验方法与实验平台，先用代料实验观测现有的设计实验装置在激波作用下是否能够实现油料的抛洒和分散，实验结果与预期相差不多后，再用瞬间释放的压力模拟激波，在一定空间下通过改变不同条件来进行实验。结果表明：一定空间内油料受到激波作用时，可以很好的抛洒雾化，如遇点火源，发生燃爆事故的可能性非常大。油料量不同，燃爆效果也不同。抛洒雾化效果越好，燃爆效果越明显。73523

Title   Experimental study on under shock wave of oil spilling and  atomization, combustion and explosion within the limited space                                             

Abstract In recent years, the demand for fuel oil is increasing for human beings, the various types of fire and explosion accidents occurred frequently。 It is difficult to control when the accident about fuel occurred。 It will cause huge casualties and property losses。 To explore under the action of shock wave of oil spilling and atomization, combustion and explosion when there is an ignition source。 We can test whether the existing experiment device can perform oil spilling and atomization by self-designing experimental method and the experimental platform under the shock wave。 If the experimental results as we expected, then we carry on the experiment by changing the different conditions in a certain space with shock wave simulation instantaneous release of pressure。 The results show that within a certain space of oil by shock wave can be atomized。 The possibility of combustion and explosion accident occurrence is very large。 The different amount of fuel, fuel combustion and explosion impact is also different。 With the atomization effect better, combustion and explosion impact is more obvious。

Keywords  shock wave, oil, spilling and atomization, combustion and explosion
