摘    要:在现有研究成果的基础上,对闸站平面不对称布置枢纽上下游水流流场的数值模拟方法进行了探讨。采用水深平均的二维水流方程可以较好地复演枢纽上游断面突缩和下游断面突扩的流速场。能贴合工程实际需要,并通过对概化模型的数值计算和物模验证,运用正交实验理论,通过量纲分析,得到处理闸站结合处导流墙的经验公式。

关 键 词:不对称水流  数学模型  物理模型  流速  试验

Abstract:Based on available research results the author probes into the numerical modeling of velocity field of upstream and downstream flow of project with asymmetric plan layout of gate and plant.Equation of two_dimensional flow of even depth is used to reproduce the velocity field of the project with sudden contraction of upstream section and sudden expansion of downstream section,thus meeting the actual requirements of the project.Through numerical calculation of the generalized model and verification by physical model,the imprirical formula for training wall at the conjunction of gate with pump station is obtained by dimensional analysis.
Keywords:asymmetry flow  numerical model  physical model  flow velocity  experimental analysis
