一、漏泄导致超声波的产生和传播 流体从机械的微隙中漏泄、或从输送流体管道的腐蚀孔中漏泄等是流体力学的一种现象。这种现象是由于压力差使高压流体(液体或气体)获得速度的缘故。因为无论对于什么样的流动现象能量守恒定律都是成立的。实际上能引起流体喷射的缝隙或破损的孔径极小,所以,这种流体 First, the leakage led to the generation and propagation of ultrasonic fluid leakage from the mechanical micro-gap, or leakage from the transmission fluid pipeline corrosion hole is a phenomenon of fluid mechanics. This phenomenon is due to the pressure difference to high-pressure fluid (liquid or gas) to obtain the speed of reason. Because no matter what kind of flow phenomena, the law of conservation of energy is valid. In fact the slits or broken pores that cause the fluid jet are extremely small, so this fluid
