| Abstract: | To study the characteristics of plasma evolution produced by metal bridge foil exploding, the experimental device of bridge foil exploding was established, and the bridge exploding experiments were conducted. Based on schlieren photography technique, the double pulse light source plasma evolution measuring system was used to observe the bridge foil exploding flow field. The schlieren pictures at different times were obtained. The shape and evolution of plasma flow field were analyzed, and the characteristic parameters of the plasma and shock wave were derived. |
