摘要:
水泵流量是确定泵站装置效率和能源单耗的关键参数,研究大型立式轴流泵进水流道两点压差式测流法具有非常重要的意义。应用基于Standard k-ε、RNG k-ε 和 Realizable k-ε湍流模型的RANS方法分别对肘形进水流道的水流流动进行数值模拟,研究了不同湍流模型在数值计算中对壁面压强的预测能力,并与物理模型试验数据进行对比,结果表明Realizable k-ε湍流模型所预测的进水流道压差与试验结果最为接近。对肘形进水流道模型在不同的流量条件下进行数值模拟,分析了壁面的压强分布规律并确定了测压点的具体位置。在肘形进水流道原型的数值计算中,采用了与模型数值计算相同的数值方法,同时引入大并行的云计算技术,预测了大型立式轴流泵现场实测流量与压差的函数关系。
Abstract:
The pump flow rate is the key parameter to determine the efficiency of the pumping station and the unit consumption of energy.It is very important to study the two-point differential pressure type flow measurement method for the inlet flow of large vertical axial flow pump.The RANS method based on Standard k-ε, RNG k-εand Realizable k-εturbulence model was used to numerically simulate the flow of the elbow inlet flow channel, and the prediction ability of different turbulence models in wall numerical calculation was studied and compared with physical model test data.The results showed that the pressure difference of the inlet flow channel predicted by the Realizable k-εturbulence model was the closest to the experimental results.The elbow-shaped inlet channel model was simulated numerically under different flow conditions.The pressure distribution on the wall surface was analyzed and the specific position of the pressure measuring point was determined.In the numerical calculation of the prototype of elbow-shaped inlet passage, the same numerical method as the model numerical calculation was adopted, and the large parallel cloud computing technology was introduced to predict the functional relationship between the measured flow rate and pressure difference in the field of large vertical axial flow pump.
