In this report, the issue of pitch control in a Vertical Axis Wind Turbine is tackled. By using and aerodynamic model, a theoretical optimum pitch solution is found and then a simple four-bar mechanism is adapted to that theoretical solution to achieve a simple and elegant control of the pitch in the turbine. The model used is the Actuator...

The aim of this thesis is to evaluate the influence between the two counter-rotating VAWT rotors with the Double Actuator Cylinder (DAC) model which will be validated against the panel code. The DAC model is developed from the original Actuator Cylinder (AC) model which includes the Modified-Linear (Mod-Lin) correction. The original AC model for...

In the last years, large scale Vertical Axis Wind Turbines (VAWTs) are re-gaining a general interest in the wind energy sector as an alternative to Horizontal Axis Wind Turbines (HAWTs). However, the existing standards and guidelines for wind turbine certification do not include specific requirements for VAWT rotors. This thesis aims to study...

The wake geometry of a Vertical Axis Wind Turbine (VAWT) is unlike the standard Horizontal Axis Wind Turbine (HAWT). The blades of the turbine continuously passes through its own wake, creating complex wake-body interactions such as flow separation and dynamic stall, and convectional grid-based numerical method which is capable of describing...
