Recent Development in the Design of Wind Deflectors for Vertical Axis
This paper reviews various designs, experiments, and CFD simulations of wind deflectors reported to date. Optimization techniques for VAWTs incorporating wind deflectors are discussed in
Investigation of fundamental mechanism leading to the performance
Wind energy utilization in urban areas revives the interests in vertical axis wind turbine (VAWT). An upstream deflector has demonstrated to increase the overall efficiency of two closely
Numerical Study of a Vertical Axis Wind Turbine with an Inner
When a cylindrical deflector of different diameters is introduced, the torque coefficient and overall performance are greatly enhanced by a 0.3-meter diameter. The cylindrical deflector''s effectiveness
Design and analysis of upstream air deflectors for increasing wind
Deflectors which will deflect the air from outer region into the region where wind turbines harness energy are employed. By doing so the flow gets accelerated and this in turn increases the
Aerodynamic efficiency assessment of a cross-axis wind turbine
The present work examines the performance of an offshore cross-axis wind turbine (CAWT) with a flow deflector by integrating numerical and analytical methods. The deflector''s
The Effect of Deflector Angle on the Performance of Turbine
This study aims to improve the performance of vertical shaft wind turbines by creating a new design combination of Darrieus and Savonius turbines with deflectors to produce CP
Improving vertical-axis wind turbine performance through innovative
In the present study, a two-dimensional VAWT is numerically modeled and simulated. Subsequently, a novel combined actuator is proposed to improve the performance of VAWT. This
