摘要
为验证玛瑙河三道坝体型设计的合理性,采用Fluent软件对三道坝流场进行了数值模拟,分析了三道坝泄流能力、水面线、底板压强、水流空化系数及典型断面流速分布等重要水力参数。数值模拟与公式计算结果吻合较好,说明数值模拟的模型建立、网格划分、边界条件定义、参数选取合适,Fluent软件能用于溢流坝的水力特性研究,可以供大坝体形优化设计参考。
To verify the design rationality of the Third Subsidiary Dam on Manao River,Fluent software is adopted to simulate the flow fields of the dam.Important hydraulic parameters,including the discharge capacity,water surface profile,pressure on the bottom plate,water flow cavitation coefficient,and flow velocity distribution on typical cross sections,are analyzed.The numerical simulation results are in good agreement with the formula calculation results,showing that the model establishment,mesh division,boundary condition definition,and parameter selection in the numerical simulation are appropriate,and the Fluent software can be used for the study of hydraulic parameters of overflow dams.The results can be useful reference for the optimization design of dams.
