中文摘要：

为了进一步有效提高屋顶风能利用的效率,在屋面之上加设一架空层,运用CFD数值模拟分析不同高度架空层对风能收集产生的影响,探讨其可行性并得出架空高度和风机安装高度最优值.研究表明：架空层的设置对增大屋顶风速有显著效果;在架空层顶板之上或之下的空间安装风力发电机,并控制架空层高度,比较分析得出合理的架空层高度和风力机的安装高度,以求达到最理想的风能利用效果.

英文摘要：

In order to improve the efficiency of wind energy utilization,an open storey is added on the roof,the influence of various open storey height to wind energy was analyzed by CFD numerical model.It＇s shown： the open storey can increase remarkably the wind speed.Installing Wind generator above or on the open storey,the influence of open storey height and wind generator height was analyzed,then the optimal heights of open storey and wind generator are obtained to achieve the maximum wind energy collection.
