Comparative Critique on Power Generation in Wind Turbines
In this study, the performance of different wind turbines is compared using Qblade software. Typically wind turbines are categorized as Horizontal Axis Wind Turbine (HAWT), and Vertical axis wind turbine (VAWT) which in this paper Darrieus type as a VAWT

Aerodynamic Performance of Vertical-Axis Wind Turbines
The nonstationary separated incompressible flows around Darrieus and Savonius rotors of vertical-axis wind turbines were investigated through computational simulation using the Reynolds averaged Navier–Stokes equations and Spalart–Allmaras turbulence ...

Vortex capturing vertical axis wind turbine [PDF]
An analytical-numerical study is presented for an innovative lift vertical axis turbine whose blades are designed with vortex trapping cavities that act as passive flow control devices. The unsteady flow field past one-bladed and two-bladed turbines is described by a combined analytical and numerical method based on conformal mapping and on a blob ...

The key components of a vertical-axis wind turbine (VAWT) are located at the base of the turbine, with the primary rotor shaft aligned transversely to the wind. Because of this arrangement, maintenance and repairs are made easier because the generator and gearbox are located close to the ground.

Structural optimization design of novel Senegal vertical axis wind turbine [PDF]
Aiming at the problem that the wind energy utilization of vertical axis wind turbines is slightly lower than that of horizontal axis wind power,a new wind turbine based on Senegalese (Senegal) type wind turbine was proposed. Firstly, the curvature of the
