集成立轴风机的高层建筑二维模型动态数值分析

摘要

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 .%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。
