摘要 在建立电弧喷射器内等离子体流场电场计算模型以及基本算法基础上,研究了采用多重网格对收敛速度的改进效果。数值计算证实了此方法的有效性尤其对流场电场耦合计算是有利的。 Calculation of electric field was one of important parts in numerical simulation of arcjet flow field.The efficiency of the calculation of the whole flow field is to most extent depending on the efficiency of this calculation and then it was necessary to take some steps to improve it.The effects of using multigrid method on efficiency improvement of electric field calculation were studied after establishing numerical model and based method on this calculation,and its special effects were verified by numerical experiments.
