梯形迷宫堰数值模拟及体型优化设计
Numerical Simulation and Research on Body Type Optimal Design Method of Trapezoidal Labyrinth Weir
摘要
Abstract
The turbulence model was applied to simulate the turbulent overflow of labyrinth weirs, VOF method which made tracks for free surface and air⁃water multiphase flow models was introduced and the computational results fitted with experimental data. The result shows that numerical simulation can be widely used to compute labyrinth weir discharge capacity and solve the discharging problems. In order to raise normal water level and realize the aim of rain and flood efficient and safe utilization, the author built a trapezoidal labyrinth weir model with design principle, objective function and constraints, used Shilu Reservoir as an example to analyze and calculate the model with UWRL flow⁃meter algorithm and then judged the feasibility with safety review methods of the dam crest elevation. The results show that using the method can not only improve reservoir flood storage capacity, but also keep the dam discharge safely, which fits the principle of rain and flood efficient and safe utilization very well.关键词
