| 摘 要： | 流体力学是航空、航天技术发展的基础,而可压流体绕流又是流体力学的一个典型问题.在二维空间中讨论可压流体圆柱绕流时速度的变化情况.首先.对具体的问题进行分析,建立数学模型(N-S方程);其次,对二维求解域进行网格剖分,在此网格图中用向后有限差分法离散微分方程,得到有关速度的方程组.最后.用Jacobi迭代法求解线性方程组,并通过C程序来实现Jacobi迭代的求解过程,把所得结果用图表示出来.

| Abstract: | Fluid mechanics is the demand of aviation and aerospace development,but compressible air flow around the column is a typical problem of fluid mechanics.This paper studies the speed change of compressible air flow around the column in the planar space.Firstly,it establishes a mathematics model(N-S equation).Secondly,it divides the planar space district,dispersing differential equation with backwards finite difference method in the grid plan,and finding equation group about the speed.Then it solves linear equ... |
