Abstract: In recent years, the need for renewable energies keeps on increasing. Thus there is a need to improve the methods for harnessing the renewable energy such as wind. One such improvement is Diffuser Augmented Wind Turbine (DAWT). Our main objective of this research paper is to optimize the Diffuser design of DAWT and to determine the maximum velocity obtained inside the diffuser for placing the blades to achieve more power output. Diffuser designs are simulated using Computational Fluid Dynamic (CFD) software ANSYS Fluent with wind inlet velocity of 5m/s and the values are compared to get a optimized model to achieve good power output. From the results, that Diffuser with flanges gives higher performance with blade located at 0.13m from the entry of diffuser which is of 1m in length. A significant increase in power is obtained which is higher than the conventional wind turbine.
