侧向稀疏波对非均质凝聚炸药冲击波起爆过程的影响
Lateral rarefaction wave effects on shock initiation of heterogeneous condensed explosives
摘要
Abstract
Pressed TNT explosive was chosen to carry out 2-D Lagrangian experiments. There lied two 2-D composite manganin-constantan (CMC) Lagrangian gauges at the same Lagrangian position. And the two gauges were placed on and off the axis, respectively. The pressure and radial displacement were measured by the CMC Lagrangian gauges embedded between individual discs of explosives. And the shock initiation process of the pressed TNT was analyzed by using the 2-D reactive flow Lagrangian analysis. At the different Lagrangian positions, some variables were gained, such as particle velocity, relative specific volume, specific internal energy, reaction rate and frozen sound speed. Results reveal the effects of lateral rarefaction waves on explosive variables during shock initiation.关键词
