摘要：
In this article, a 3D computational study has been performed to understand the flow phenomenon over the vertical axis wind turbine with a three-bladed NACA0021. The rotary motion ofthe VAWT simulated with sliding mesh techniques with reference to the SST-K omega turbulence model using the CFD software. The observed results were found to be having a significant improvement in the enhancement ofthe power output. Also, the investigation was move forwarded to understand the flow characteristics of the VAWT with the presence of deflector plates in different orientation at the upstream conditions. The present of deflector plates creates an augmented flow phenomenon which creates an acceleratedflow at the near wake region, causing a significant improvement in the coefficient of power of the wind turbine.
