风光塔式发电装置风道的模拟分析

Scenery Tower Power Plant Simulation Analysis of Wind Tunnel

通过建立风光塔式发电装置风道的三维模型,运用ICEM CED划分网格,FLUENT软件进行数值分析,采用其中的RNG k-epsilon湍流模型,对风道内的速度场、压力场等进行模拟,得到了风道内的风速分布及压力分布的具体情况。模拟的结果显示风速达到了40m·s^(-1)以上,压力沿着流道入口到出口迅速降低,湍流动能在临近出口处最大。

Tower power plant by building beautiful three-dimensional model of wind tunnel,using ICEM CED to mesh,FLUENT software for numerical analysis,using one of the RNG k-epsilon turbulence model,simulating the velocity field of wind tunnel,pressure filed and so on,obtained the wind speed distribution and pressure distribution of the specific circumstances in the wind tunnel.Simulation results showed that wind speed reached 40 m·s^(-1) or more,pressure quickly lowered along the flow channel from inlet to outlet and turbulent kinetic energy was the largest near the exit of the wind tunnel.
