箱装发射药储存时的安全性及能量分析

Analysis of the Safety and Energy Content of Ammunition Stored in Cases

采用大型通用计算程序 PHOENICS(1.4版本 )对箱装发射药中含有内部热源的非稳态导热与自然对流换热及辐射换热的耦合问题进行了数值求解。分析和比较了在直角坐标和贴体坐标下发射药内部靠近中心处的最高温度随时间的变化趋势 。

The conjugate heat transfer analysis of transient thermal conduction, natural convection and thermal radiation in a case with ammunition, which is a temperature dependent heat sources, was simulated numerically using PHOENICS (Version 1.4). The variation of the maximum temperature and the self ignition hazard in the ammunition was analyzed using both body fitted coordinates and cartesian cordinates. The safety and energy content in the ammunition were analyzed for various storage conditions.
