    摘要:

    为解决引江济淮跌水、跌井汇流口水流水力特性模拟问题,采用基于 VOF 法的 RNG k-ε 双方程紊流数学模型对杨大庄跌水工程进行三维数值模拟研究,通过计算结果与已经完成的水工模型试验结果相对比,验证该模型模拟杨大庄跌水工程水流的水力特性的可行性。 研究结果表明:通过合理的处理网格及计算参数,杨大庄跌水水流入渠的流态、流速分布及水位数值模拟结果整体与试验值吻合较好,说明利用该模型模拟杨大庄跌水工程水流的水力特性是可行的,数学模型可用于指导和解决类似工程问题。

    Abstract:

    In order to solve the problem of simulating the hydraulic characteristics of the confluence estuary of the water diversion from the Yangtze-to-Huaihe River and the well, the RNG k-ε two equation turbulent mathematical model based on VOF method is used to conduct a three-dimensional numerical simulation study on the Yangdazhuang drop project. The feasibility of this model in simulating the hydraulic characteristics of the water flow of the Yangdazhuang drop project was verified by comparing the calculation results with the completed hydraulic model test results. The research results show that through reasonable treatment of grids and calculation parameters, the numerical simulation results of the flow pattern, velocity distribution and water level of the Yangdazhuang drop into the channel are in good agreement with the experimental values, indicating that it was feasible to use this model to simulate the hydraulic characteristics of the Yangdazhuang drop project, and the mathematical model can be used to guide and solve similar engineering problems.
