根据电熔爆单脉冲电弧的物理模型,结合磁流体动力学与麦克斯韦方程组,建立电熔爆电弧等离子体的二维数学模型;通过对模型控制方程组和边界条件的数值处理,基于FLUENT二次开发软件,对电熔爆单脉冲稳态电弧进行数值模拟;根据模拟结果分析电熔爆等离子体的温度场、速度场和压力场,并与相关文献结果进行对比,验证了模拟仿真的正确性,有助于电熔爆技术的持续深入研究。

According to the physical model of Electrical Melting and Explosion （EME） single pulse arc, a two-dimensional mathematical model of EME arc plasma is established based on the magnetic fluid dynamics and Maxwell＇ s equations. By the numerical treatment of control equations and boundary conditions,the numerical simulation of the single pulse steady state are is carried out based on secondary development of FLUENT software. Based on the simulation results, such as temperature field, velocity field, pressure field, and so on, compared with the related literatures, the correctness of the simulation is verified, which is helpful to the further research of EME technology.
