Vertical Axis Wind Turbine Evaluation and Design

There are two main types of wind turbines. The two general categories for wind turbines include vertical axis or horizontal axis wind turbines. The turbines are classified upon how the shaft of the generator is mounted. The horizontal axis wind turbine HAWT was invented before the vertical axis wind turbine (VAWT), which led to its popularity and

Review of Specific Performance Parameters of Vertical Wind ...

The vertical-axis wind turbine (VAWT) with drag-type rotor models provides lower performance values, but they benefit from constructive cost advantages, an easy starting possibility, and operation at lower wind velocities [1,2,3,4].

Design of a vertical-axis wind turbine: how the aspect ...

This work analyses the link between the aspect ratio of a vertical-axis straight-bladed (H-Rotor) wind turbine and its performance (power coefficient). The aspect ratio of this particular wind turbine is defined as the ratio between blade length and rotor radius. Since the aspect ratio variations of a vertical-axis wind turbine cause Reynolds number variations, any changes in the power ...

Vertical axis wind turbine technology continues to improve

1.3 How to design a good small vertical-axis wind turbine 1.3.1 Although different from a HAWT, the core technology of a VAWT remains a wind mill structure with blades. After choosing an airfoil, it is necessary to calculate a concave orientation, angle, width, and quantity because each of these factors determines the performance of the VAWT.
