中文摘要:针对泵站过水建筑物中出现大量的泥沙淤积和不良流态,基于欧拉固液两相流模型对大型泵站进水侧流场进行三维CFD数值模拟。数值模拟结果表明,泵站原始的布置方案会引起低速区、漩涡以及回流等不良的进水流态,会导致在泵站前池出现泥沙淤积的现象。为了改善泵站进水流态和减少前池的泥沙淤积,对泵站分水堰形状进行修改并在引渠段加设整流底坎。数值模拟结果显示,通过对泵站原始布置方案的修改,消除了前池内的回流,漩涡的范围也有所减小,泥沙淤积的现象得到了较大的改善,水流中的泥沙体积分数平均减少了13%。

Abstract:Sediment deposition in the pumping station has a huge negative impact on unit operation. 3-D CFD method was used to simulate pumping station inlet structure flow based on Eulerian solid-liquid two-phase flow model. Numerical results of preliminary scheme show that sediment deposition occurs in the forebay of pumping station because of poor flow pattern therein. In order to improve hydraulic configuration in the forebay, one modified measure was reconstructing water diversion weir shape, and another measure was setting a water retaining sill in the approach channel. The simulation results of modified scheme prove that back flow in the forebay was eliminated and sediment deposition region was also reduced greatly.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
