Abstract

We set up an experimental apparatus to investigate the micro shock wave with high experimental efficiency. We have performed the micro shock wave visualization with schlieren method by using laser induced plasma, which generated by a focusing pulsed CO₂ laser. The propagation and reflection of the shock waves are investigated. Additionally, a numerical simulation for compressible and inviscid flow is also performed to understand the propagation characteristics. As a consequence, our experimental apparatus is very convenient to simulate the explosion phenomena. Moreover, the result from a numerical simulation shows an agreement with the experimental results.
