Abstract

The intention of this investigation is heading for development of a “Duct Enhanced Wind Turbine (DEWT)” system to reduce the tip losses incurred and to increase the amount of power produced when compared to an unducted wind turbine. The use of a “Diverging Duct” over an unducted turbine amplifies the mass flow and airstream velocity at the turbine blades thereby increasing the power created by the turbine for a given air speed. The project also aims to design this DEWT system as small and light enough to be installed on rooftops of urbanized buildings. The project aims at analyzing a wind turbine augmented with a diverging duct so as to determine its power output and compare it with that of an unducted turbine. The analysis is centered on finding out how the use of a uncomplicated duct over a wind turbine will improve the power generated by it. The estimation of velocity increase at the duct inlet and the functions of additional add-ons such as the inlet cowl and the exit flange have been done. The model was modeled and meshed by using commercial modeling and meshing software’s and the flow was simulated in commercial CFD software. The analysis has been done to replicate the flow of the fluid within, over and around the turbine blades. It was found by Numerical Computations that the use of a Diffuser duct helps in increasing the air velocity at the immediate entry of the wind turbine for a given air velocity. It was observed that for a given air velocity of 9 m/s, the velocity at the inlet was found to be 13.9846 m/s which are 55.4% increase in velocity. Also, the power extracted by a Ducted Wind Turbine was found to be increased by a factor of 4.86 than that of an unducted wind turbine.
