摘要
应用CFD方法,对不同来流方向的气流绕流某科技馆不规则顶部的流动情况进行了模拟计算。根据分析计算结果发现,不同方向来流的流动所受到的该建筑物屋顶的影响差别很大。为了避免屋顶气流绕流对垂直轴风力机运行产生的不利影响,只要适当调整垂直轴风力机在屋顶上的安装高度,就可以使东、西两侧垂直轴风力机摆脱屋顶气流绕流产生的涡流区,达到改善垂直轴风力机的运行状况的目的。
In this paper, the wind field of a Science and Technology Museum roof is simulated by CFD. According to simulation, it is found that the airflow in different directions is seriously influenced by buildings roof. In order to avoid the adverse effects caused by airflow around buildings to the running of the vertical axis wind turbines, the height of the vertical axis wind turbines is adjusted. As a result, the vertical axis wind turbines are removed from eddy cavities and run in good conditions.
