| 摘 要： | 本文对使用流体动力学碰撞模型研究球形靶等离子体鞘层时空演化的求解过程进行了详细的讨论,利用迎风差分格式求解流体力学方程,将泊松方程线性化后,利用三对角矩阵“追赶”法对其进行求解,使整个计算过程收敛速度较快,提高了整个方程组的求解速度,得到了与解析结果一致的数值计算结果.

| Abstract: | In this paper,the evolution of the plasma collisional sheath in spherical geometry has been numerically simulated using a collisional fluid dynamic model. The numerical simulation method is easy to be performed,and the convergence velocity is rapid. The fluid dynamic simulation of collisional sheath evolution in spherical target has been compared successfully with analytical results. |
