摘要
讨论有限长锥管内的低雷诺数入口流问题，用Ｓａｍｐｓｏｎ解展开流函数成无穷级数，系数由边界条件用配置法确定，用最小二乘法和修正的Ｇｒａｍｍ－Ｓｃｈｍｉｄｔ正交化方法求解矛盾方程组，并画出了相应角度的入口流速度剖面．
The present paper deals with the entrance flow at low Renold number in a finite circular cone.The collocation method is used to solve this problem.In order to overcome the ill-conditioning of the matrix of the linear system,the least-square method and the modified Gramm-Schmidt orthogal process are used.Finally the velocity distribution in the entry region is obtained.
