摘　　要：介绍建筑环境中的风能利用基本形式及风能利用可行性评价指标.针对安中大楼所处的特定位置,运用计算流体力学方法对周围的风环境进行数值模拟;对可能利用风能的位置即风速明显增大区域,如夹道、洞口及屋顶处进行详细的分析,利用风速增大系数指标评价风能利用的可行性,对合理布置风力机提出建议.研究结果表明:在夹道处、大楼边角处风速加大,可以安装小型风力发电机,综合考虑经济性和有效性,可以沿塔架高度布置多台水平轴风力机;建筑物开洞区域的风速增大,风向平行于洞口径深时效果显著,适合在洞口前沿布置水平轴风力机;安中大楼屋顶风速较大,集结效果明显,可以根据屋顶尺寸安装多排风力机.Basic forms of wind power generation in built environment and some indexes which evaluate the feasibility of wind power utilization were introduced. Considering the special location of Anzhong Building, the wind field around building was simulated by the computational fluid dynamics method. Some special places with large wind velocity, such as passageway, wind ductand building roof, were chosen to conduct further analysis. The utilization feasibility was evaluated using the index of wind speed increasing coefficient and proposals about reasonably installing wind turbines were proposed. Results show that the wind velocity at the building corner and passageway increases obviously and micro-turbines can be installed here. Considering economy and efficiency, it is feasible to install some horizontal-axis wind turbines on tower along the height. In the wind duct of the building, the wind velocity also increases significantly, especially when the direction of wind is parallel to that of the duct depth. The horizontal-axis wind turbine is suitable to be located at the front edge of duct. The wind power concentration effect on the roof of Anzhong Building is obvious with the increasing wind velocity, and multi rows of wind turbines can be installed according to the size of roof.
