该文以火炮射击安全性为背景 ,利用两相流理论建立了火炮膛内过程的点传火优化仿真模型。以膛内压力波作为优化目标 ,对药包点火和中心点火管点火2种不同的点火方式进行了点传火条件的优化分析 ,并与实验结果进行了比较 ,两者有较好的一致性。这说明基于两相流动理论的优化仿真模型具有一定的可信度 ,它必将为火炮的装药及其点传火设计提供一种新的理论方法和工具 Based on the shooting safety of artillery, this paper established a point-propagation fire simulation model based on the two-phase flow theory. Taking the pressure wave in the borehole as the optimization target, the optimization of point-by-pass fire conditions was carried out for two different ignition modes of the ignition of the medicine packet and the ignition of the center ignition tube, and the results were compared with the experimental results. The two have better consistency . This shows that the optimization simulation model based on the theory of two-phase flow has a certain degree of credibility and it will surely provide a new theoretical method and tool for artillery charge and point-fire design
