Vertical-axis wind turbines feature a design where the blades spin around a vertical shaft. This allows them to capture wind from any direction without requiring adjustments. In contrast, horizontal turbines have a more aerodynamic design that demands alignment with the wind direction, achieved through yaw mechanisms.
This research work aims at designing a small-scale Vertical Axis Wind Turbine (VAWT) with suitable blade pitch control which would be useful in improving its performance. A three-bladed H-type Darrieus VAWT is considered with the NACA0021 airfoil as the blade cross-sectional profile.
Fig. 7. Test configuration for cooling tower with VAWTs and enclosure . Most of the studies on VAWTs are focused on the design and power coefficient efficiency when installed into a building. The studies explored the design and placement of vertical axis wind turbines (VAWTs) in urban environments.
Kuang et al. proposed the building augmented vertical axis wind turbine (BA-VAWT) design that takes advantage of windy areas in the built environment to generate power. The study was conducted to determine the aerodynamic performance of the turbine using numerical simulations and the NACA 0021 blade aerofoil.
Vertical axis turbines typically convert only 35%–40% of wind energy into electricity, compared to 40%–50% for horizontal axis turbines. Some blades face drag during rotation, which reduces efficiency and increases mechanical strain. Vibration and turbulence near ground level can lead to frequent wear and tear, increasing the need for repairs.
VAWTs typically achieve 35%–40% efficiency, which is lower than the 40%–50% efficiency range of horizontal-axis turbines. This gap exists because some blades on a vertical turbine face the wind directly during rotation, creating drag forces that reduce overall energy capture.
