Abstract
Pressure decrease of the shock wave is investigated at reflection from the end of the shock tube channel passing through a sand layer. The influence of the layer location on the pressure pulse extension and on the decrease of the maximal pressure amplitude behind the shock wave is studied. A shock tube was consisted of high-pressure and low-pressure chambers in 72 × 72 mm2 square cross sections. The high-pressure chamber represented a “short” section, 25 cm long, to create the shock wave with the decreasing profile. The impact of a shield made of granulated material on attenuation of the shock wave multiply reflected from walls is investigated at an explosion inside a closed volume. We performed the experiments in the shock tube with a short high-pressure chamber. The low-pressure chamber was filled with air at atmospheric pressure. The flat blast wave with the reducing pressure profile was created. We discover the dependency of the pressure reduction at the reflected wave front on the distance between the protecting shield and the closed end of the shock tube.
