Effect of Pitch Parameters on Aerodynamic Forces of a Straight-Bladed Vertical Axis Wind Turbine with Inclined Pitch Axes

Pitch regulation plays a significant role in improving power performance and achieving output control wind turbines. The present study focuses on novel, pitch-regulated vertical axis turbine (VAWT) with inclined pitch axes. effect of two parameters (the fold angle the incline angle) instantaneous aerodynamic forces overall straight-bladed VAWT under tip-speed ratio 4 is investigated using an actuator line model, achieved ANSYS Fluent software validated by previous experimental results. results demonstrate that has apparent influence angles attack blades, as well turbine. It helpful to further dynamic adaptable passive VAWTs. Incline away from 90° lead asymmetric distribution along blade span, which expected reduction loads main shaft tower
