Abstract

Wind energy is one of the most promising renewable energy resources. BAWTs have been studied recently. BAWTs are a new technology trend to combine wind turbines with buildings and structures and it has several advantages compared with the conventional wind turbine such as minimization of electrical transmission loss and construction cost due to the distributed power sources and using buildings. In this paper, 110 kW class horizontal axis wind turbine is designed and CFD analysis is carried out with various wind speed. The results show aerodynamic power output of 110 kW class BAWT is higher than that of 110 kW class stand alone wind turbine due to the concentration effect caused by the wind speed acceleration between buildings. Flow characteristics are quite different for the existence of 110 kW class BAWT. These results can be applied to the research and development of BAWTs and high performance computing is indispensable.
