摘要
泄水建筑物下泄水流通常具有复杂的三维水流特性,常规的一维或者平面二维技术无法精确模拟其流态。应用三维数值模型对水闸、溢洪道、拱坝等泄水建筑物三维水流进行数值模拟,并与水工模型试验成果进行对比。数值模拟计算的水面线、流态及流速分布均与水工模型试验实测资料吻合较好,表明三维数学模型可以结合水工模型试验解决泄水建筑物常规水力学问题,为工程设计和运行提供相关的技术依据。
Discharge flow of discharge structures usually have complex three - dimensional flow characteristics. The conventional one-dimensional or two- dimensional planar technology can not accurately simulate the flow pattern. Three - dimensional numerical model was applied to simulate three- dimensional flow discharge structure sluices, such as spillway, arch dam and so on, compared with the results of hydraulic model test. The water lines, flow pattern and velocity distributions of numerical simulation results are in good agreement with the measured data of hydraulic model test, which showed that three - dimensional mathematical model can be combined with hydraulic model tests to solve conventional hydraulics problems of discharge structure, providing related technical basis with the engineering design and operation.
