Abstract

![CDATA[Using CFD simulations, a small conventional horizontal axis wind turbine (HAWT) Ampair 300 was installed in a confined flow space: through-building openings embedded at different levels of a tall building. The openings were located at 1/3, 1/2, 2/3 and 5/6 of the height of the building. The flow characteristics within the through-building openings when the building is exposed to a realistic wind profile have been investigated and applied to a single through-building opening including the small HAWTs. Four small HAWTs were located in the middle of each opening with a 3m × 3m cross-section area. Power generation and performance of the small turbines operating in the opening was investigated and compared with when installed in the free stream condition. It is shown that a confined space prevents flow from bypassing the turbines and increases the flow rate passing through it which results in power generation augmentation. For further flow enhancement, a compact diffuser was also integrated with the turbine and significantly enhanced its performance and power generation. This study shows that integration of wind turbine in a confined space with suitable design can enhance its performance and offers a potential location for integrating small wind turbines in an urban building.]]
