The increase of world oil price could destabilize the economy of developing countries, including Indonesia. Various efforts by the Government of Indonesia in its efforts to save the state of energy supply have been implemented including making various policies concerning new and renewable energy. Wind energy is one type of renewable energy sources that is potential to be developed in Indonesia. However, the unique character of the wind need for special studies in their implementation. <br /> <br /> <br /> Computational Fluid Dynamics (CFD) model is one model that can be used to determine the performance of wind turbines. CFD simulations can be used to calculate the turbine’s efficiency curve and also the speed and air pressure that <br /> <br /> <br /> can be used as the basis for the optimization. <br /> <br /> <br /> Optimization performed on various types of configurations including variations of shroud diameter, the number of baffles and shroud profile. Velocity of air inside the shroud at each configuration were compared, and design that <br /> <br /> <br /> gives the maximum velocity was selected. The final optimised design was then simulated in three dimensions, constructed, and then tested in the wind tunnel. <br /> <br /> <br /> As the conclusion, a shroud with 4,5 m diameter, four baffles and with profile convex is the best configuration. The test results show a significant improvement in performance, gaining velocity from 160 rpm without shroud to be 450 rpm with a shroud.
