An Investigation on Performance of Shrouding a Small Wind Turbine with a Simple Ring in a Wind Tunnel
Ducted wind turbines are a kind of small wind turbine having a diffuser or any other shape around the rotor which increases the air flow through the blades and absorbs more power. In the present study, a small wind turbine was ducted with a relatively simple ring and its performance was investigated in a wind tunnel. The duct is shaped using rolling steel sheets on a sloping surface and finally...
متن کاملA Shrouded Wind Turbine Generating High Output Power with Wind-lens Technology
We have developed a new wind turbine system that consists of a diffuser shroud with a broad-ring brim at the exit periphery and a wind turbine inside it. The shrouded wind turbine with a brimmed diffuser has demonstrated power augmentation by a factor of about 2–5 compared with a bare wind turbine, for a given turbine diameter and wind speed. This is because a low-pressure region, due to a stro...
متن کاملUpgrading a Shrouded Wind Turbine with a Self-Adaptive Flanged Diffuser
In this paper, a self-adaptive flange is proposed for the wind turbine shrouded by a flanged diffuser to reduce the wind loads acting on the flanged diffuser at high wind velocities. The self-adaptive flange can maintain the advantages of the flanged diffuser at wind velocities lower than the rated velocity and reduce the wind loads acting on the diffuser and blades at higher wind velocities. N...
متن کاملDesign and performance of a cm-scale shrouded wind turbine for energy harvesting
A miniature shrouded wind turbine aimed at energy harvesting for power delivery to wireless sensors in pipes and ducts is presented. The device has a rotor diameter of 2 cm, with an outer diameter of 3.2 cm, and generates electrical power by means of an axial flux permanent magnet machine built into the shroud. Fabrication was accomplished using a combination of traditional machining, rapid pro...
