CFD Modeling and Design of Wind Boosters for Low Speed Vertical Axis Wind Turbines

Abstract:

In Thailand, the average wind speed is generally quite low (≈ 3 - 4 m/s). Although Vertical Axis Wind Turbines (VAWTs) are designed for low speed wind, standalone VAWTs are still unable to generate power satisfactorily under that practical condition. This study introduces a new design of a wind flow controlling device, called a “wind booster”, by utilizing Computational Fluid Dynamics (CFD). A wind booster is developed for incorporating with a VAWT in order to increase the performance of the VAWT and to overcome the limitation of harvesting energy with low availability at low speed wind. The guiding and throttling effects of the optimal design of the wind booster are able to increase the angular velocity of VAWTs which leads to an increase in power generated from VAWTs.
