该文针对采用配水整流措施的侧向进水泵站,基于对集水池流场的CFD数值模拟,采用单因素数值试验方法研究配水孔面积和配水孔高宽比这两个几何参数对水泵进水条件的影响,并利用射流理论解释其影响机理。研究结果表明:要想获得稳定良好的水泵进水条件,配水孔面积应等于或大于进水喇叭口直径的平方,配水孔高宽比应等于或大于2倍的单元集水池的水深池宽比。 Based on the CFD numerical simulation of the flow field in the catchment, aiming at the lateral inlet pump station adopting the water distribution rectification measures, the single factor numerical test method was used to study the influence of the water hole area and water hole aspect ratio on the water inflow conditions The influence of jet theory is explained. The results show that in order to obtain a stable condition of the pump inlet water, the water hole area should be equal to or larger than the square of the inlet flare diameter and the water hole aspect ratio should be equal to or greater than 2 times the water depth of the unit sink.
