摘要:
采用RANS方法，基于湍流模型开展了施桥闸站进水流态的数值模拟研究，观察了泵站进水流态及各断面流态，分析进水池泵前纵剖面轴向速度分布均匀度、速度加权平均角。计算结果表明：沉螺池内形成2个大尺度低流速回流区，前池进口附近处存在低流速回旋区，出口附近流态较好，进水池中层及底层流态平顺，进水池轴向流速分布基本均匀对称，研究成果可为同类泵站设计提供参考。
Abstract:
Based on the turbulence model, the RANS method was used to carry out the numerical simulation study of the inflow flow pattern of Shiqiao Gate Station, observe the inflow flow pattern of the pump station and the flow pattern of each section, and analyze the axial velocity distribution uniformity and the velocity weighted average angle of the longitudinal section in front of the pump in the intake pool. The calculation results show that there are two large-scale low-velocity circumfluence zones in the settling basin for oncomelania snail, there is a low-velocity circumfluence zone near the inlet of the forebay, the flow pattern near the outlet is good, the flow pattern in the middle and bottom of the intake tank is smooth, and the axial velocity distribution in the intake tank is basically uniform and symmetrical. The research results can provide reference for the design of similar pumping stations.
