摘要 基于长距离引水的多系统输水泵站的安全运行要求,以三维CFD仿真模拟和物理模型试验交互进行多方案比较和设计优化。经采用导流墩、底坎、进水孔等整流措施进一步改善水力条件和配水均匀性,实现进水流道的水流条件平顺、流态稳定,泵站万吨水占地仅为常规设计的50%,进、配水建筑物的沿程最大水位落差较经验参数设计法减少58%,达到了系统稳定可靠和节能减排的双重目标。 Based on the safety operation requirements of water delivery pump stations for long-dis- tance water diversion, the muhiple scheme comparison and design optimization were performed by combi- ning 3-D CFD numerical simulation and physical model experiment. Hydraulic rectification measures such as guide piers, bottom sills and water holes were taken to improve hydraulic conditions and water distribution uniformity, which achieved smooth and stable flow in the inflow channel. The footprint of the pump station per 10 000-ton water was only 50% of the conventional design. The maximum height of wa- ter along the water intake was 58% less than that of the empirical parameter method. The dual goals of stable and reliable system, energy saving and emission reduction were achieved.
