Behaviors of bubble jets induced by underwater.explosion of cylindrical charges under free-field conditions
摘要
Abstract
Underwater explosion experiments were carried out for PETN cylinders in a water tank and elementary data about bubble motions under free-field conditions were obtained by using the highspeed photography technology. Results show that the bubble dynamics of cylindrical charges differs from those of spherical ones, and charge mounting modes affect markedly bubble behaviors. For a horizontally mounted cylindrical charge, asymmetric collapse is achieved due to the asymmetric motion of the bubble interface. As a result, an asymmetric jet is formed and the width of the jet varies with the length-diameter ratio of the charge. On the other hand, for a vertically mounted cylindrical charge, a symmetric jet is generated due to the axial symmetric motion of the bubble interface. In the case of equal-weight charges, the velocity of the jet generated by the vertically mounted cylindrical charge is higher than that generated by the horizontally-mounted one.关键词
