N2 - Diffuser augmented wind turbines (DAWTs) offer more energy efficient of production of wind power as compared to conventional wind turbines. In this paper, the mass flow rate of air through the diffuser is increased by addition of slits at the inlet section and designing of the diffuser is done using airfoils. The Reynolds averaged Navier–Stokes equations (RANS) are used along with k- SST turbulence model to calculate the power and thrust coefficients and to visualize the flow inside and outside the diffuser. These results are obtained by generation of geometry using CATIA and running the simulations in ANSYS Fluent. Grid convergence study is done for verification of these results prior to further analysis.
