Abstract
From a safety engineering viewpoint, it is important to predict the motion of flying fragments generated during accidental explosions. In our previous work, a special shock tube system to study the shock-induced motion of a solid body suspended in the air was constructed, and then the shadowgraph images of the shock-induced motion of a solid body were acquired by using a high-speed camera. It was found from the previous work that the body's motion was affected by the flow between the body and the floor, and the initial attack angle of the solid body. In the present study, we have observed the shock-induced motion of a solid body with relatively large, initial attack angle by Schlieren photography technique. The present results show how the initial posture of the solid body and the flow field around the body influence the body's motion.
