Experimental Studies of Shock Induced Particle Jetting

The dispersion of a cylindrical ring by a shock wave takes the shape of particle jets. Based on the quasi-two-dimensional experimental platform, the formation of particle jets in the inner surface of the particle ring is observed. It is found that the jets is generated by the inner surface of the particle ring and then develops to the outer surface. When the impulsive loads change, the shape and distribution of the jets change too. The number of early internal jets is basically the same. As the impulsive loads increase, the number of late internal jets decrease gradually. When the impulsive loads become greater, the distribution of particle jets will be more uneven, and the larger jets will merge the surrounding smaller ones during the dispersion of the particle ring, which leads to the decrease of the number of jets.
