摘要:
为探究一体化泵站在不同流量工况下泵站内部流动特性,基于不可压缩流体的连续性方程和雷诺时均N-S方程,采用计算软件CFD对一体化泵站进行数值模拟。通过不同特征工况下,分析了一体化泵站内部流动相关特性及水力性能影响。结果表明:小流量工况下,入水口流速平缓,集水池内流线上下扩散严重,多处出现漩涡,水泵效率偏低,随流量稍增,两水泵效率偏差增大; 大流量工况下,水泵效率下降快,流线向管道Ⅰ偏流。从而在过小或过大流量工况下,会对一体化泵站的高效与经济运行产生一定影响。
Abstract:
In order to investigate the internal flow characteristics of the integrated pumping station under different flow conditions, the numerical simulation of the integrated pumping station was carried out by using the calculation software CFD based on the continuity equation of incompressible fluid and the Reynolds time-averaged N-S equation. The internal flow characteristics and hydraulic performance of the integrated pumping station were analyzed under different characteristic conditions. The results showed that under the condition of small flow rate, the inlet flow velocity was gentle, the flow line in the catchment pool was diffused seriously up and down, there were whirlpools in many places, and the pump efficiency was low. While under the condition of large flow rate, the pump efficiency decreased quickly and the streamline deflected to the pipeline I. Therefore, it would have a certain impact on the efficient and economic operation of the integrated pumping station when it's too small or under the condition of excessive flow.
