泵站前池与进水池整流方案数值模拟OA北大核心CSCDCSTPCD
Numerical simulation of flow pattern modification schemes for the forebay and suction sump of pumping station
针对田山一级泵站采用闸门控制前池与进水池水位形成闸下射流的引水特点,提出了改善前池与进水池水流流态的不同整流方案.采用雷诺时均N-S方程结合标准k-ε的湍流模型,对不同整流方案的前池与进水池水流流态进行数值模拟,分析并选择了合适的整流工程措施.模拟结果表明,采用非连续底坎、非连续挑流坎与压水板三种整流措施相结合的方案后,整个前池与进水池内的流态得到较好地改善,池底部及水泵进口处的流速明显减小且能够有效避免与减小前池内、底坎与挑流坎后的泥沙淤积.现…查看全部>>
At the Tianshan first-grade pumping station, water level of the forebay and suction sump is controlled by a sluice at the forebay inlet. To improve flow patterns formed by the jet under the sluice, the RANS equations and a standard k-ε turbulence model are used to simulate the flow and to study different schemes. Simulation results show that the most effective scheme is the one combining three engineering measures, non-continuous bottom sills, non-continuous…查看全部>>
