Aerodynamics and aero acoustics studies of VAWT; computational studies using LES

The harnessing of wind energy has received significant interest in past decades. Therefore, in the past decade the use of wind turbines in the urban areas has also been explored. However, the use of wind turbines in the urban areas poses some challenges due to the noise levels. To assess the feasibility of using the wind turbines in the urban areas, the aero acoustics of wind turbine must be addressed. Experimental studies of wind turbine pose significant challenges due to the rotating frame of reference and costly experimental setup. Therefore, computational approaches are a promising alternative to the costly experiments. This research concerns the aerodynamics and aero acoustics of vertical axis wind turbine using a Darrieus turbine design. The computational studies are performed for three different wind speeds V=3m/s, V=5m/s and V=7m/s.
