环形射流,环形喷口;
Hence, jet tip velocity produced by direct annular initiation is higher than that of plane initiation, and plane initiation higher than point initiation. It is also concluded that the jet tip velocity of plane and annular initiation increases as the initiation radius increases.
环形起爆形成的射流头部速度高于面起爆的,面起爆高于点起爆的,并且随着起爆直径的增大,面起爆与环形起爆所形成的射流头部速度逐渐增大。
