We design ducted wind turbines based on the features used to determine the sizes and indices of wind tunnels. Many researchers used analytical and numerical methods to select the optimized duct. This study evaluates the effect of design parameters, such as nozzle length, contraction ratio, and outlet diameter, on multiple responses.
The open circles denote the ducted wind turbine. When the duct was included, the power output increased dramatically. The Bergey, for example, produced roughly 700 W at 9 m/s, whereas the Clarkson open rotor configuration produced about 925 W. The power of the turbine was improved to around 1880 W once the duct was built.
Therefore, it is crucial to create novel wind-capturing equipment that can produce power in sites where conventional horizontal-axis wind turbines are impractical to build and maintain. Ducted Wind Turbines (DWTs) have been developed to improve wind turbine performance throughout the past few decades.
Ducted Wind Turbines (DWTs) have been developed to improve wind turbine performance throughout the past few decades. The enclosed wind turbine exceeded the open rotor by a slight margin in terms of total cross-sectional area, exceeding the Betz limit.
