摘要:
烘箱试验有时无法获得物料在烘烤过程中的详细温度分布。基于计算流体力学仿真手段，针对某高氯酸盐与奥克托今(HMX)两种不同固体含能材料的烘箱试验烤燃过程，开展了三维数值仿真研究。通过数值仿真，获得了烘箱试验升温过程中的热传递规律以及物料内部各区域温度的分布与变化情况。结果表明：两种样品在当前体系下发生热爆炸之前，最高温的热点位置都处于样品中轴线偏上位置；高氯酸盐的热爆炸时间为46 551 s，HMX的热爆炸时间为14 703 s。仿真结果与烘箱试验结果基本一致。
Abstract:
In the oven test, it is impossible to obtain the detailed temperature distribution of materials during baking. Therefore, based on computational fluid dynamics simulation method, three-dimensional numerical simulation research was carried out for the baking process of two different solid energetic materials, a perchlorate and HMX. Through numerical simulation, the heat transfer law during the heating process of the oven test and the distribution and variation of temperature in various areas inside the two materials were obtained. The results indicate that, before thermal explosion occurs in the current system, the hottest hot spots of both samples are located above the axis of the samples. The thermal explosion time of the perchlorate is 46 551 s, while that of HMX is 14 703 s. The simulation results are basically consistent with the oven test results.
