摘　　要：水膜蒸发空冷器百叶窗按仰角进风方向安装时,管束下方迎面风速为双峰状。用Fluent软件数值研究的结果表明,百叶窗叶片仰角大于60°时,管束下方的风速很不均匀;百叶窗叶片仰角为15°时,管束下方的风速基本均匀。百叶窗叶片仰角从上到下分别取60°、45°、30°和15°时,管束下方的风速也基本均匀。The wind velocities under the tube bundle impacted by the elevation angle of the louver board were studied with the numerical simulation software Fluent.When the louver boards inclination is paralleled to the elevation angle of the wind,the profile of distribution for the wind velocities under the bundle becomes the pattern in twin peaks.The greater the elevation angle of the boards,the more uneven the wind velocities under the bundle.The wind velocities under the bundle will be approximately uniform if the elevation angles of the boards take 15° or arrange respectively in 60°,45°,30° and 15° from the top to the bottom.
