TVD格式在等离子体增强含能材料燃烧模拟中的应用

APPLICATION OF TVD SCHEME FOR THE SIMULATION OF ETC GUN INTERNAL BALLISTICS

建立了描述等离子体增强含能材料燃烧的一维两相流模型 ,用该模型可以模拟电热化学发射装置的点传火过程并预测压力波 .应用TVD算法完成了模型的编码 .文中给出了模拟结果 ,结合 30mm口径的发射实验进行了对比分析 。

A one dimensional model was developed for the simulation of 30mm ETC gun internal ballistics, and a second order TVD scheme was employed for the code in order to improve the computational stability. This code can be used to simulate the process of ignition and combustion of SPETCG, and to predict the pressure wave. Agreement was shown in comparison with the measured results of 30mm ETC gun firings.
