6 FAQs about [Generator wind shroud soft connection]
Does a shrouded wind turbine improve performance?
Furthermore, our own testing verifies that a shrouded turbine increases performance over a comparably-sized, unshrouded wind turbine. The way the shroud connects the nacelle to the tower provides passive yaw so the wind turbine can adapt to changes in wind direction.
Can a shroud be used as a wind vane?
This would allow the majority of the surface area of the shroud to act as a wind vane. The comparison of small-scale wind turbines by Cui, Yu, Liu, and Whitty, allowed us to intuitively design a shrouded wind turbine that will align with the incident wind .
How does wind affect a shroud design?
Induced forces from wind on the shroud design. These induced moments about the yaw axis will eventually settle to equilibrium. From our wind tunnel and real world experiments, we have seen the equilibrium settle to where the wind vector is normal to rotor plane.
Can a shrouded wind turbine align with an incident wind?
The comparison of small-scale wind turbines by Cui, Yu, Liu, and Whitty, allowed us to intuitively design a shrouded wind turbine that will align with the incident wind . Incident wind can impact the rotor cross section at an angle, where the component normal to the rotor cross section is the force on the rotor.
What is a rotor shroud?
The shroud is a diverging diffuser located directly behind the rotor. Its purpose is to create a low-pressure region behind the turbine rotor which increases the wind speed incident on the rotor. Multiple academic articles were our inspiration for a shrouded design.
Why do we have a shroud?
The design includes a shroud as a way to decrease cut-in speed, increase our coefficient of power, and provide torque for yaw control. The nacelle was designed to support the shroud as well as house the electrical components. The tower has been designed to accommodate yawing while supporting the turbine assembly.
