Study on Shock Wave Pressure Attenuation by Shock Wave Interaction with Water Droplets

This paper reports preliminary experimental results of shock wave/ water droplets interaction phenomena related to shock wave pressure attenuation. Water droplets were generated by dropping from a several needle pipes, were interacted with micro-explosive-induced shock wave. The process of induced spherical shock wave/ water droplets interaction phenomena was visualized by shadowgraph method and recorded by a high-speed camera. The pressure histories of propagated shock wave interacting with water droplets were measured simultaneously by using the pressure transducer. High-speed shadowgraph sequential images show that interacted water droplets were highly deformed, and a wave front of a secondary shock wave was decayed. The simultaneously measured pressure history shows that a primary shock wave peak pressure was attenuated with interacting at water droplets, and a peak pressure ratio was decreased.
