摘要:本报告汇编了过去 21 年在劳伦斯利夫莫尔国家实验室获得的爆热和产品成分数据。在每次测定中,25克高爆装药在炸弹热量计中引爆; 1至2小时内完成完整的量热测量,精度为O.3%。使用热力学和流体力学计算机计算来解释数据。对于无约束或轻度约束的电荷,释放的能量大部分保留在产物中,随后通过炸弹壁的反射而使产物大大偏离查普曼-茹盖等熵线。对于严格约束的装药,爆轰能大部分转化为约束情况的动能和内能,并且产物沿着查普曼-茹盖等熵线以最小的再冲击膨胀。
Abstract : This report is a compilation of heat-of-detonation and product-composition data obtained at Lawrence Livemore National Laboratory during the last 21 years. In each determination, a 25-g high-explosive charge was detonated in a bomb calorimeter; a complete calorimetric measurement was made in 1 to 2 h with a precision of O.3%. Data were interpreted using thermodynamic and hydrodynamic computer calculations. For unconfined or lightly confined charges, the released energy is largely retained in the products, which are subsequently shocked considerably off the Chapman-Jouguet isentrope by reflections from the bomb wall. For heavily confined charges, the detonation energy is largely converted to kinetic and internal energy of the confining case, and the products expand with minimal reshock along the Chapman-Jouguet isentrope.
