Abstract

Abstract

According to the dispersal mixing process of explosive-driven solid powder and liquid, a transparent double-layer dispersal device was designed.A high-speed photography system was used to record the shell crushing of the dispersal device and the evolution of the solid-liquid interface and dispersal cloud status.The crack in the shell appeared and the shell fractured first along the axial direction of the shell.Before the outer shell broke, the solid-liquid interface was clear, which indicated that the solid powder and liquid mixed mainly after the shell failure.The detonation waves driven by the detonating cord presented sliding-detonation characteristics, the dispersal cloud shape took on an inverted truncated cone, and the cloud movement velocities at the different sections were inversely proportional to the axial distance of the sections from the initiation location.
