中文摘要: |
为了比较定常多相位与非定常计算方法在双吸离心泵中的应用情况,文章对150S 50双吸离心泵内部湍流流场进行了模拟计算。数值模拟采用Realizable κ-ε湍流模型,在7种工况下分别用定常多相位和非定常2种方法进行了模拟计算。在数值模拟的基础上计算出扬程、轴功率、效率。研究表明:用非定常模拟所得计算结果与试验值更为接近。 |

In order to compare the steady multi phase and unsteady calculation in double suction centrifugal pump application, this article simulated the internal turbulent flow of the 150S-50 double suction centrifugal pump.Numerical simulation adopted realizable turbulence model and simulating calculated with two methods of steady multi-phase and unsteady in 7 cases. Based on the numerical simulation to calculate the head, shaft power and efficiency, the results show that: the results of unsteady simulation are closer with the experimental data. |
