摘要
本文在现有研究成果的基础上,提出了一种汊点分组解法其特点是能够根据实际问题的需要,灵活方便地将河网中的汊点划分为任意多组,使汊点方程组的系数矩阵压缩到与分组后每组中的汊点数相同的阶数不仅极大地压缩了系数矩阵的贮存量,而且计算量大幅度减少。
In this paper,a junctions group method is proposed for unsteady flow.The junctions group can be divided easily in computational practice and the coefficient matrix dimension can be reduced arbitrarily.Thus not only saves the computational time and storage but also offers high accuracy.
