摘要:
以平山堂取水泵站为例，在分析原始方案进水池流态的基础之上，提出了改善进水池内水流流态紊乱、泥沙淤积的整流措施。采用Fluent流体软件，以两相流理论为基础，选取Realizable k-? 湍流模型及DPM泥沙流模型，对泵站整流前后进水池内的流态进行了数值模拟。结果表明，采用抬升进水箱涵底板高度和压水板组合优化方式后，相关区域内水流流态明显好转，且泥沙淤积现象得到了缓解，平均含泥量下降75%，进水池内泥沙淤积基本消除。研究结果可为类似工程进水池流态改善提供参考价值。
Abstract:
Taking Pingshantang Pumping Station as an example, measures for fluid meliorating and sediment deposition controlling were put forward based on the analysis of the original flow regime in the pump sump. The numerical simulation of the pumping station before and after rectification is carried out with the application of FLUENT software. The results are based on the two-phase flow theory, and the standard k-? turbulence model along with DPM sediment flow model were used during the simulating process. The result shows that the flow regime in relevant areas has been improved significantly after taking the combined optimization method of lifting the bottom plate height as well as adopting a water pressure board. The problem of sediment deposition has been alleviated, and the average sediment content decreases by 75%. The sediment accumulation almost disappears in pump sump. The research results could provide certain reference value for the improvement of the flow regime of similar pump sumps.
