基于FLOW-3D软件的块体水垫塘消能机理数值模拟

Numerical Simulation of Energy Dissipation Mechanism in Block Plunge Pool Based on FLOW-3D

针对目前高坝水垫塘形式存在的缺点,采用FLOW-3D软件模拟了块体与平底水垫塘内水流的运动特性,结合平底水垫塘的消能机理,对比分析了块体水垫塘的水流流态、流速衰减和消能率等。结果表明,块体水垫塘消能效果较好,数值模拟方法准确性较高。

For the current shortcomings of high dam in different water plunge pool,FLOW-3Dsoftware is used to simulate the flow motion characteristics in the block and flat plunge pool.Combined with energy dissipation mechanism of the flat plunge pool,the flow pattern,velocity of flow attenuation and energy dissipation rate of the block plunge pool is comparative analysis.The results show that the effect of energy dissipation for block plunge pool is better,and the numerical simulation accuracy is relatively high.
