- 摘要:
- 离心泵是国民经济各部门必不可少的机械设备，其内部流场的流动极为复杂，因此需用高效的数值模拟方法对其进行研究，从而指导实际应用，为泵的改良设计提供可靠依据。现利用商用CFD软件Fluent对IS140-125-400型蜗壳式离心泵进行整机的流场模拟，在动参考系坐标下，用有限体积法对雷诺时均N-S方程进行离散，选用标准的k-ε湍流模型和SIMPLEC算法进行求解，分别得出离心泵在不同流量工况下的速度和压力分布图，真实地反应出泵内部的流动情况，并对其进行分析和比较，得出泵在靠近额定工况下运行时，流动最稳定。

- Centrifugal pump is indispensable mechanical equipment in national economic sectors.The flow in the internal flow field is very complex.Thus it is necessary to use an efficient numerical simulation method to study them to guide practical application and provide reliable basis for the pump to improve and design.Using the commercial CFD software Fluent to simulate the machine of the flow field of IS140-125-400 type spiral centrifugal pump，in the frame of moving reference coordinate，using the finite volume method to disperse the Renault time-averaged Navier-Stokes equations.Selecting standards of k-ε turbulence model and SIMPLEC algorithm to solve and obtained the velocity and pressure distribution of the centrifugal pump respectively in different flow condition，which could real react the internal flow of the pump.Through the analysis and comparison，the conclusion was drawn that when it was running under near the standard conditions，the pump flow was the most stable.
