| The combination of the sluice and pump station is more and more widely used, because it has the advantage of the construction of the gate station. It can save the engineering investment, reduce the occupied area, facilitate the effective management and so on many merits. And combined sluice pump shape tend to be more beautiful, can become a tourism scenic area. But compared with the form of the gate station, there are some disadvantages.Due to its structural layout, flow pattern of combined sluice pump did not build good. But when the operation is easy to form reflux and drift caused by water flow, confusion, influence of efficient operation of sluice gate station. Therefore, when taken jointly built in the form of sluice gate station shall fully consider the flow regime, efforts to improve the water inlet and outlet flow, so as to improve the operating efficiency of the gate station.The paper based on the Haiyang Jing sluice station as engineering background, using gambit and fluent numerical simulation software, creating a reasonable 3D model, studies the sluice station water inlet and outlet flow, and puts forward the measures to improve it.1. the research and development of the flow characteristics of the asymmetric hub of the gate station are summarized, and the existing problems and their hazards are analyzed and discussed.2. Based on the existing gate station is the hub of the construct reasonable 3-D hydrodynamic mathematical model, the standard model, by using the simple algorithm, given a reasonable boundary conditions, the pumping station before the pool water inlet and outlet flow of 3D numerical simulation.3. single factor analysis method is used to calculate and analyze the factors that affect the flow pattern of the water inlet and outlet of the sluice gate station. The influence of the length of the diversion wall and the arrangement of the baffle wall on the flow pattern is analyzed comprehensively. |
