Theoretically it is proved that the performance of bare wind turbine cannot exceed the Betz-Joukowsky limit but this limit can be exceeded if the turbine is placed inside the optimized diffuser. This research work presents the analysis of diffuser augmented wind turbine (DAWT) using dynamic meshing where the turbine was rotated with the effect of wind and the angular velocity of the wind turbine was calculated for different flow velocities and this result was compared with the results of bare wind turbine. The DAWT results show more than 700% increase in turbine angular velocity. CATIA V6 was used to design the wind turbine and ANSYS Fluent was used to carry out the simulation.
