Abstract
Wind energy is a green and sustainable system and vertical axis wind turbines (VAWT) have been developed for low speed operation as small wind turbines. CFD simulations can be conducted to save time and cost. The design structure of the VAWT wind turbine used CFD software for the operation of stream lining. This investigation involved the designs of Model A and B, the Benesh type matched by Model A and the Semicircular type matched by Model B. The CFD simulation compared Cp and TSR values between using Model A and Model B wind turbines. Model A exhibited a 0.24 Cp maximum matched by 1.22 TSR, this model could produce high performance when compared to Model B. Model A could be increased by 4.8 times the Cp value when compared with Model B. The 3D velocity streamlines and corresponding vector plots at various angular positions can be performed using the wind flow with corresponding Cp values.
