“…Aravindhan N [6] et al found that the output power of ducted wind turbines can be significantly increased as compared to open rotors and discussed the installation of such wind turbines on the on top of or around a building and discusses the power generated by installing such a wind turbine on top of or around a building. In addition, Aravindhan N [7] has conducted a study on the performance of a shrouded INVELOX small wind turbine in two scenarios: a low-rise building and the top of the tallest building in order to investigate the effect of the shroud profile on wind speed. Aravindhan N [8] et al examined the potential productivity of wind turbine installations in urban areas and investigated the feasibility and success of small and medium-sized turbines in community residences.…”

In this paper, a wind collection device (WCD) is designed for vertical axis wind turbine, and the WCD and vertical axis wind turbine are modelled by SolidWorks software and numerically simulated by CFD software FLUENT for the WCD and vertical axis wind turbine before and after installing the WCD. The wind amplification effect of the WCD is demonstrated from different angles and the final results show that the WCD can amplify the wind speed from 5m/s to 8m/s and double the rotational speed of the wind turbine in a certain area, which is of certain reference significance in the field of wind power generation using traffic wind energy.

Effect of flanged diffuser divergence angle on wind turbine: A numerical investigation

et al. 2023

Power augmentation in a small-scale horizontal axis wind turbine, with its rotor encased in a flanged diffuser is explored. The power output of the wind turbine varies with changes in the diffuser design and the resulting back pressure. Reduction in this back pressure also results in early flow separation at the diffuser surface, which hinders turbine performance. The main aim of this study is to numerically investigate the local configuration of the wind turbine location inside the diffuser by varying diffuser angles and wind speeds. Therefore, shroud and flange were modeled and analyzed using the computational fluid dynamic (CFD) analyses and experiments were performed at two wind speeds 6 m/s and 8 m/s with and without the diffuser for model validation. The divergence angle of 4° was found to have no flow separation, thus maximizing flow rate. The proposed design shows wind speed improvement of up to 1.68 times compared to the baseline configuration. The corresponding optimum flange height was found to be 250 mm. However, increasing the divergence angle had a similar output. The dimensionless location of wind turbine was found to be between 0.45 and 0.5 for 2° and 4° divergence angle respectively. Furthermore, the maximum augmentation location varies with wind speed and diffuser’s divergence angle as described by dimensionless location of wind turbine, thus presenting a noteworthy contribution to the horizontal axis wind turbine area with the flanged diffuser.
