摘　　要：在理论分析的基础上 ,结合实验条件建立了液体发射药电热化学发射内弹道一维两相流数学模型 ,该模型包含电弧等离子体生成和运动、等离子体卷吸液体发射药生成小液滴以及膛内多相流体的相互作用。利用该模型对电热化学发射内弹道过程进行了数值模拟 ,并将模拟结果与实验数据进行了分析比较 ,结果表明模拟结果与实验数据基本吻合。Based on the theoretical analysis and experiments, an 1 D two phase interior ballistics model of electrothermal chemical(ETC) launching is presented in this paper,which consists of the flow of discharge plasma, the formation of propellant droplets under the entrainment of plasma jet, and the interaction of multi fluid in ETC chamber. The launching process in interior ballistics is numerically simulated, the comparison of simulation results with experimental ones indicates that the simulation agreed well with the experiments.
