Numerical method for unsteady flow in lock manifold

摘要: 在考虑了阀门井水流、各水头损失及廊道和支孔惯性长度的影响之后，推导了船闸廊道复合管非稳定流的基本方程组。阐述了解该方程组的一种数据值迭代方法。计算结果表明，该方程迭代过程稳定、收敛速度较快，且与试验实测值较为吻合。

Abstract: The basic equations describing unsteady flow in lock manifold are derived, in which various hydraulic loss and inertia head of culvert and ports are included. A numerical iteration method for solution of the basic equations is developed. The results show that the iteration procedure is steady and its convergence is fast. Comparing with the laboratory data, the calculated value is in agreement with the observed.
