The objective of the present work is to increase the effectiveness of the wind turbine explicitly without changing the design parameters of the existing wind turbines. Deflectors which will deflect the air from outer region into the region where wind turbines harness energy are employed. By doing so the flow gets accelerated and this in turn increases the mass flow rate. This reduces the cut in speed for the wind turbine setup. The present work focuses on simulation for flow over the deflector to study the nature of this setup. The simulation was performed for different angle of deflector and at different velocities and the results are presented. Results highlight the significance of such deflectors in improving entire efficiency of the system.
