摘    要：本文采用最小二乘配置法求解异型管流问题。计算结果表明,该法具有很多优点:收敛稳定;计算程序简单;机时消耗少;准备工作量少;且一经计算完成,残值即可得到。

Abstract: In this paper the least square collocation method of computing the flow in non-circular ducts is presented.As shown by all concrete examoles,the presented method possesses those advantages,such as stability in convergence,simpler computer program,less time consumption,less amount of work and residuals may be known immediately after computation.
