摘  要:
以150QJ20型深井泵为例,利用CFD软件Fluent快速准确地预测深井离心泵的性能,分别用不同网格数、不同残差收敛精度、不同湍流模型、不同流场计算方法进行了数值模拟,分析了不同设置方法对数值模拟结果的影响;对不同级数深井离心泵模型的数值模拟结果进行了讨论。在此基础上,选择出适合深井离心泵的数值模拟设置方法。将数值模拟结果与试验结果对比,分析了两者的差异,表明了利用F luent软件预测深井离心泵性能的可行性。

摘  要:
In order to predict the performance of deep-well centrifugal pump quickly and accurately by the commercial CFD software Fluent,150QJ20 type deep-well centrifugal pump was taken as an experimental object to research the key set methods on the Fluent simulation.The numerical simulation was carried out at different grid numbers,different residual convergence precisions,different turbulence models,and different flow calculation methods to analyze the impact on simulation results.And different stages of the deep-well centrifugal pump model simulations were analyzed and discussed.The best set methods of numerical simulation for deep-well centrifugal pump were selected.The differences between numerical simulation and experimental results were compared and analyzed.This work is real significance in understanding the accuracy for deep-well centrifugal pump,and it confirmed the feasibility of predict the performance of deep-well centrifugal pump by using Fluent.
