Wind energy is a significant contributor to global renewable energy production. 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. The enclosed wind turbine exceeded the open rotor by a slight margin in terms of total cross-sectional area, exceeding the Betz limit. In this particular scenario, carrying out this one easy step results in a nearly 16 percent improvement in the power coefficient. This study will cover the ducted wind turbine idea employed by several researchers, as well as the results provided for the building of a mathematical model and comparison to experimental data. Many studies have come to the same conclusion, which is that the power output of ducted wind turbines can be increased by somewhere between five and six times that of conventional wind turbines.
