【摘要】 针对江都三站进水流道存在的问题,采用三维紊流数值模拟计算的方法对其进行了优化水力计算,并采用透明流道模型试验的方法对数值模拟的结果进行了验证。计算和试验结果表明:优化方案与现状进水流道相比,不仅消除了流道内的涡带,而且进水流态均匀、水力损失小,已达到正常进水流道的水平,可应用于江都三站改造。更多还原

【Abstract】 Aiming at the problem existing in the inlet elbow of Jiangdu No. 3 pumping station, method of 3D turbulent numerical calculation was applied to optimize the inlet elbow, and method of model test of transparent inlet elbow was applied to verify the calculation results. The results of both calculation and test make it clear that the optimum scheme not only eliminate vortex bent in the inlet, but also improve flow pattern and reduce hydraulic loss of the inlet. Consequently, the optimum scheme has achieved the normal level and can be used for the reformation of Jiangdu No. 3 pumping station.更多还原
