Abstract

The recent renewable energy grows significantly concerning on people awareness of the negative effect toward environment. Based on the advantages that should be offer by Vertical Axis Wind Turbine (VAWT) becomes an interested object to be observed. Especially VAWT Darrieus, H-Rotor type. Not only known has simple structure but also has higher efficiency than Savonius. Airfoil Profile becomes substantial because its aerodynamic effects which run on the Darigus turbine. Numerous pevious studies observed that the use of asymmetric airfoil gives advantage toward Darrieus turbine efficiency. In this case, this research focuses on the influence of cambered airfoil toward the maximum potition to the turbine performance. The Investigation is observed using Computational Fluid Dynamic (CFD) which is two dimentions Darrieus turbine type H-Rotor turbine model is simulated in trancient current condition. In result, the simulation as power coefficient presented the best turbine performance is conducted by airfoil with the maximum camber potition close to the trailing edge. While the variation on the chord length gives a solidity ratio of 0.6 as the best value between the above and below.
