该文研究了多层壁面有限长轴对称火药颗粒床中药粒的传热过程，采用热电偶对药粒的温度场进行实验测定。理论计算时，利用控制容积法导出了１组差分离散格式，并在计算机上进行了数值模拟。结果表明，数值解与实验值基本一致，从而为发射装药实时平均温度的确定奠定了基础。经进一步研究，有可能广泛适用于目前现装备火炮及未来各类火炮弹药温度对初速修正的需要，同时也可推广到不便直接测温的填充床等化工系统。
In this paper, we study the heat transfer process of granules in a finite length axisymmetric gunpowder bed with multi-layer walls. The thermocouple was used to measure the temperature field of the granules. In the theoretical calculation, a set of differential discrete schemes was derived by the control volume method and was numerically simulated on a computer. The results show that the numerical solution is basically consistent with the experimental value, which lays the foundation for the determination of the real-time average temperature of the propellant charge. After further study, it may be widely applied to the current needs of artillery and various types of artillery ammunition temperature correction for early velocity, but also can be extended to the inconvenience of direct temperature measurement of the packed bed and other chemical systems.
