| 摘 要： | 本文研究了半无限长圆管内Stokes流的入口流问题.我们导出了一种新的级数解,它与文献[1,2]的解有一个明显的区别就是该解中不包含无穷积分,因此有利于计算.本文利用配点法进行了计算,得到了满意的结果.

| Abstract: | The problem of Stokes entry flow into a semi-infinite circular cylindrical tube was studied in this paper. A new kind of series solutions was derived. Their evident difference from the solutions in References [1,2] is that the present solutions don't involve infinite integral. So they are favourable for calculation. We calculated an example by allocated method and obtained satisfied results. |
