采用标准k-ε湍流模拟方法,在不考虑风力机与建筑连杆及风力机叶尖损失的影响下,采用滑移网格技术,对风力机与建筑一体化二维模型在不同风速下进行动态研究。结果表明:在不同风速下,建筑迎风面风力机的转矩系数最大值为0.41,最小值为0.10;背风面风力机的转矩系数最大值为0.27,最小值为0.17。
採用標準k-ε湍流模擬方法,在不攷慮風力機與建築連桿及風力機葉尖損失的影響下,採用滑移網格技術,對風力機與建築一體化二維模型在不同風速下進行動態研究。結果錶明:在不同風速下,建築迎風麵風力機的轉矩繫數最大值為0.41,最小值為0.10;揹風麵風力機的轉矩繫數最大值為0.27,最小值為0.17。

This paper used the standard k-ε turbulence method and sliding mesh technique to research the two-dimensional model of building integrated with wind turbine under different wind speed,and the torque coefficient of wind turbine and physical properties of whole flow field were analyzed without consid-ering the impact of the connection between building and wind turbine and the speed loss of blade. The re-sults show that:Under different wind speed,the maximum value of torque coefficient of wind turbine on the windward side is 0 . 41 ,the minimum value is 0 . 10;the torque coefficient of leeward side maximum value is 0 . 27 ,the minimum value is 0 . 17 .
