| 摘 要： | 为了计算针对外加轴向磁场的同轴等离子体发生器内等离子电弧的运行轨迹和旋转速度,采用了数值分析方法。首先采用通道模型计算了电弧半径;将电弧等效为刚体,根据电弧稳态旋转阻力力矩与电磁力矩平衡原理建立了其稳态运行的数学模型,然后通过采用禁忌搜索算法计算了其转速。研究结果表明:粒子的空间运行轨迹为近似平面抛物线以阴极为对称轴旋转形成的空间迹线。此外,实验结果证明了理论工作的有效性和正确性。

| Abstract: | In order to calculate the revolution locus and speed of arcs inside a coaxial plasma generator, a numerical model and method was proposed, The channel model was used to decide the radius of the arc, while the revolution speed of the arc was determined form the mathematical model based on the balance of damping and driving electromagnetic torques of a rigid body using a tabu search algorithm. Numerical results indicate that the trajectory of the plasma arcs in 3D is formed by the rotation of a 2-D parabola locus. Also, the proposed work is validated by the primary tested results. |
