塑料导爆管反应区温度分布的近似计算

Approximate Calculation of the Temperature Distribution in a Detonating Nonel Tube

导爆管爆轰可近似地处理成气相爆轰,因而可给出其爆轰参数;文中采用高速摄影观测了两种导爆管(普通导爆管和煤矿导爆管)反应区长度,并对其进行了理论计算;在此基础上作合理近似与假设,推导出一组温度计算公式;用迭代法计算可得到导爆管反应区内的温度分布。此外,对导爆管传爆中的某些现象也作了分析。

The process of detonation in a nonel tube can be treated approximately as that of the gas-phase detonation and the detonation parameters can thus be determined. The length of the reaction zone of two types of nonel tube, common type and coal mine permissible type, are observed by high-Speed photography and theoretical calculation of that are also carried out. A set of formulas for temperature calculation are derived by appoximation. The temperature distribution in the reaction zone of a detonating nonel tube can be determined by iterative computations. In addition, some phenomena involved in the detonation process of a nonel tube ate also reviewed.
