中文摘要:
      针对溢洪道迷宫堰过流形态复杂的问题,采用FLUENT软件,运用VOF方法、RNG κ ε双方程紊流模型,结合ICEM CFD软件划分网格,对山区峡谷型水库溢洪道单宫V型迷宫堰过流能力进行三维数值模拟,在分析正堰、侧堰和宫头过堰水流流态、流速矢量分布及压力变化的基础上,得到不同单宫角度V型迷宫堰的过流能力,并将数值计算结果与物理模型试验数据进行比较。结果表明,模拟值与试验值误差在允许范围内,能够满足工程要求。研究结果可为工程设计提供参考。
英文摘要:
      In order to solve the complicated flow state of labyrinth weir in the spillway, based on the FLUENT software and mesh partition with the ICEM CFD software, the VOF method and the RNG κ ε turbulence model were used to carry out three dimensional numerical simulation of flow ability of mono palace V type labyrinth weir in the canyon style reservoir spillway. The flow state, velocity vector distribution and pressure change of different mono palace angles in positive weir , side weir and head weir were analyzed, and the flow capacity of V type labyrinth in different mono palace angles was obtained. Compared with the results of numerical simulation and physical model experiment, the results show that the errors of both simulation and experiment values are within the permissible range, and it meets engineering requirements. The research results can provide reference for engineering design.
