某节制闸水流流动特性数值模拟研究

Numerical Simulation of Flow Characteristics of a Controlled Sluice

为研究节制闸泄流时水流流动规律,节制闸过流时上下游水流流态、流速分布及水面线,基于三维水流数学模型,利用FLOW-3D软件、RNG k-ε模型和VOF法分析不同工况、不同闸门开度下节制闸水流流动特性。数值模拟结果可为节制闸的运行管理及优化调度提供科学依据。

In order to investigate the flow pattern,velocity distribution and surface line of the upstream and downstream flow in the controlled sluice flow,the flow-3 d software,RNG k-ε model and VOF method were used to analyze the flow characteristics of the controlled sluice flow under different working conditions and different gate opening degrees. The results of numerical simulation can provide scientific basis for the operation management and optimal scheduling of the controlled sluice.
