Abstract


In recent years, China is vigorously developing western inland navigation to promote the economy of the western regions. A large number of inland navigation facilities are being or will be constructed. Thus the issues of the filling and emptying system adjusting to high head or superhigh head navigation lock on the mountain rivers such as type selection, layout and its related hydraulics will become the research focus of the current and future navigation hydraulics.On the basis of analyzing the dissipation principles and the hydraulic characteristics of the filling and emptying system with chamber wall’s long culvert and short side orifice outlet, the application of energy dissipation sill in system is studied for the first time in this paper, for that the flow and berthing conditions in the chamber are well ameliorated, the layout of filling and emptying system in lock chamber can also be further simplified. The study adopt the analysis method which about techniques of physical models, and three-dimensional mathematical model to contrast diverse layouts of the energy dissipation sill for energy dissipation effects. With international advanced turbulent compute software fluent, hydrosphere VOF two-phase model to trace free surface and RNG k-εturbulent model, the paper make numerial simulation for 3D flow field. Analyzing carefully computing fruits, some conclusions are got as follows:1. Computation and measure inosculate preferably ,which proved numerical simulation is effective . Numerical simulation can offer vast information about flow field to reflect entirely flow structure and energy dissipation process as powerful makeup of physics model.2. the layout of energy dissipation sill provides a stable and sound working condition for the valves, and most of the water energy is dissipated before entering into the lock chamber. therefore, the flow and berthing conditions in the chamber are well ameliorated, the layout of filling and emptying system in lock chamber can also be further simplified.3. Computation and measure inosculate preferably ,which proved numerical simulation is effective . Numerical simulation can offer vast information about flow field to reflect entirely flow structure and energy dissipation process as powerful makeup of physics model. Filling and emptying system with chamber wall’s long culvert and short side orifice outlet with energy dissipation sill can better meets the characteristics of lock buildings of china, it is a new layout type of filling and emptying system for the low head and navigation lock. The achievements in this paper can be used for references for the design and construction of the high head navigation locks in china.
