| 摘 要： | 本文在N—S方程涡量一流函数形式的经典ADI格式和SOR松驰迭代公式的基础上,对其“外来项”进行平均化处理,构造出了平均化差分格式及迭代求解程序。对雷诺数Re=100,1000,10000的空腔流动分别进行了数值计算,并与各数值方法的结果及实验资料进行了比较,结果令人满意。

| Abstract: | Based on the ADI methods (Alternating Direction Implicit) and SOR methods (Successive Over Relaxation) for solving the Navier-Stokes equations utilized the vorticity-stream function approach, averaging those terms calculated from other partial differential equations called as "outer term" an averaging finite difference scheme for 2-D flows were proposed in this paper. A 2-D driven cavity flow was calculated numerically as an example with the schemes at R.=100, 1000, 10000. The results were discussed and compared to those obtained from other numerical methods as well as experimental data. The a-greement is quite satisftory. |
