摘要
为了研究金属氢化物对燃料空气炸药（FAE）破坏力的增强，使用 20 L 球形爆炸试验系统并结合比色测温技术，探讨了金属氢化物（TiH2、MgH2、ZrH2）粉末对纯环氧丙烷（PO）冲击波和热破坏的影响。实验结果表明，与基本金属粉末相比，含有金属氢化物（TiH2、MgH2、ZrH2）粉末的固液混合燃料的爆炸超压、最大压力上升率和最大平均温度分别增加了 11.04%、22.61%、4.80% 和 26.68%、38.18%、13.91%，以及 6.85%、8.57%、1.34%。此外，金属氢化物粉末对云爆燃料的影响优于铝粉，而 MgH2 粉末对纯 PO 的破坏力增强效果最为显著。金属氢化物粉末作为高能添加剂可改善 FAE 的能量释放特性。
Damage power enhancement of fuel air explosive with typical metal hydrides additions
To study the damage power enhancement of fuel air explosive (FAE) with metal hydrides, the effects of metal hydrides (TiH2, MgH2, ZrH2) powders on shock wave and thermal damage of pure propylene oxide (PO) were explored using a 20 L spherical explosion test system combined with colorimetric thermometry technology. The experimental results showed that compared with the base metal powders, the explosion overpressures, maximum pressure rise rates and maximum average temperatures of the solid-liquid mixed fuel with the metal hydrides (TiH2, MgH2, ZrH2) powders increased by 11.04 %, 22.61 %, 4.80 % and 26.68 %, 38.18 %, 13.91 % as well as 6.85 %, 8.57 %, 1.34 %, respectively. Furthermore, the effects of metal hydride powders on the cloud explosion fuel were better than those of Al powders, and MgH2 powders had the most significant effects on the damage power enhancement of pure PO. Metal hydride powders as high-energy additives could improve the energy release characteristics of FAE.
期刊介绍：
Case Studies in Thermal Engineering provides a forum for the rapid publication of short, structured Case Studies in Thermal Engineering and related Short Communications. It provides an essential compendium of case studies for researchers and practitioners in the field of thermal engineering and others who are interested in aspects of thermal engineering cases that could affect other engineering processes. The journal not only publishes new and novel case studies, but also provides a forum for the publication of high quality descriptions of classic thermal engineering problems. The scope of the journal includes case studies of thermal engineering problems in components, devices and systems using existing experimental and numerical techniques in the areas of mechanical, aerospace, chemical, medical, thermal management for electronics, heat exchangers, regeneration, solar thermal energy, thermal storage, building energy conservation, and power generation. Case studies of thermal problems in other areas will also be considered.
