摘　　要：以建于弯道处某实际工程水库为例,采用旋桨式流速仪和流场时测系统对弯道处某实际工程水库闸孔泄流的水力特性进行了系统的物理模型试验研究,对比运用FLOW-3D软件建立的数学模型,验证了3种不同工况流量下闸孔水流泄流时的泄流流态、流量水位关系、水舌挑距和挑高、表面流速分布、中孔的泄流水面线、溢流面压力分布和尾坎处的流速,显示了数值模拟的准确性,验证结果与模型试验结果基本一致,吻合较好,为类似工程研究提供了重要参考依据。The physical model test of the hydraulic characteristics of the reservoir is taken as an example to study the hydraulic characteristics of the physical model test on the discharge elbow of the sluice gate in the practical project by using the propeller type velocity meter and the flow field measurement system,and comparing the mathematical model established by the FLOW-3D software to verify the three kinds of flow under different operating conditions.The flow pattern,the relationship between the flow and water level,the distribution of the surface flow velocity,the pressure distribution on the surface of the discharge surface.The verification results are basically consistent with the model test results,and the kissing effect is good,providing similar engineering research.Important reference basis.
