鹅颈水库至茜坑水库供水工程进水口方案分析

Analysis of Water Inlet Scheme for Water Supply Project from Gooseneck Reservoir to Xikeng Reservoir

为了研究鹅颈水库至茜坑水库供水工程进水口方案的合理性,采用CFD数值分析法从流态、流速、水头损失等3个方面进行研究。结果表明:进水口流线较顺畅,流速分布均匀;库区平均流速小于0.2 m/s,不会发生冲刷,拦污栅断面平均流速0.34 m/s;水头损失亦满足相关规范要求,可为类似工程提供参考借鉴。

In order to study the rationality of the water inlet scheme of the water supply project from Gooseneck Reservoir to Xikeng Reservoir,the CFD numerical analysis method was used to study the flow pattern,velocity and head loss.The results show that the inlet flow line is smooth and the velocity distribution is uniform.The average flow velocity in the reservoir area is less than 0.2 m/s,and no scour will occur.The average flow velocity in the section of the sewage barrier is 0.34 m/s.The head loss also meets the requirements of relevant specifications,which can provide reference for similar projects.
