- 摘要:
- 基于Navier-Stokes方程组和标准k-ε湍流模型,对高速离心泵不同工况下进行了全流道数值模拟。为了验证诱导轮对高速泵性能的影响,设计两个不同的模型进行模拟,分析了泵内的压力场和速度场的变化规律,并预测出其性能曲线。分析表明,在相同流量下,诱导轮使高速泵具有更好的流动特性,可以提高泵扬程、效率。采用数值计算方法可以预测高速泵的性能,并由水力试验得到了验证。
- Abstract:
- Based on Navier-Stokes equation set and standard k-ε turbulence model, the full passage numerical simulation of a high-speed centrifugal pump was performed in different working condition. Two different models and their simulations were designed to verify the influence of inducer on the performance of the high-speed centrifugal pump. The variation of velocity and the pressure fields inside the pump are analyzed in detail so as to predicate the pump performance curve. The analysis result shows that the high-speed pump with inducer have better flow characteristics under the same flow rate and the inducer can improve the efficiency and head of the pump. The performance of high-speed pump can be predicted by numerical calculation method. The conclusions made above were verified by hydraulic test.
