摘　　要：现采用Fluent软件进行数值模拟,结合高水头平板闸门小开度的水工模型试验,对影响闸后水流特性的主要因素闸前水头和闸门开度进行研究,运用Fluent软件建立合理的数学模型进行模拟计算,并将计算结果与物理模型试验实测数据进行对比,两者吻合良好,且能较好反应平板闸门小开度闸后水流特性。表明应用数值模拟的方法研究平板闸门小开度闸后水流特性是可行的,并对数值模拟结果进行分析,得到相关规律。The universal software Fluent is used to develop a numerical simulation to study the two important factors,the upstream water-level and gate opening,on the downstream flow characteristics of the sluice gate with small opening.Meanwhile,the results from a hydraulic model test for the sluice gate with high water level and small opening are used to compare with those obtained from the numerical simulation.Both the physical and numerical models provide similar results on flow characteristics,which suggests that the numerical simulation to obtain the hydraulic characteristics of the sluice gate with small opening is applicable.The model results are analyzed and the corresponding flow characteristics of the sluice gate with small opening are discussed.
