    摘要:

    列出了用边界拟合坐标表示的涡量一流函数绕流计算偏微分方程组,及其交替隐式有限差分和显式有限差分方程组。用自动调控边界计算了矩形区域单园柱绕流运动,其有无穷域绕流特征。绘制了速度矢量分布图,和流函数,涡量,两个分速度及压强的等值线分布图。

    Abstract:

    In this paper, partial differential equations of vortex flow-stream function in boundary fitted coordinates and related ADI equations were listed. The flow around a cylinder in quadrilateral area by auto control boundary was computed. The diagram of distribution of speed arrow, constant lines of flow-stream function, vortex, two speed parts and pressure were studied.
