Computational Fluid Dynamics (CFD) is a tool that can offer the best solution to understanding the characteristics of straight Darrieus wind turbine. A CFD program could run numerical calculations with time as parameter input (unsteady condition). Efficiency curve can be obtained from the simulation and it could be used as a method for optimizing the design of wind turbine. Several configurations were optimized such as variation of solidity, number of blade, thickness, and chamber length. Efficiency curves of each configuration are compared to obatin the optimum design. The final result of optimizing was also simulated in 3 dimension. The main weakness of straight Darrieus wind turbine is its inability of selfstarting. This problem can be solved with some modifications such as combination of Savonius-Darrieus or twisted blade. One of these modifications will be chosen based on its advantages and disadvantages. Airfoil NACA 0015, 3 blades, solidity of 0.4, diameter of 1.5 m, height of 1.5 m with twisting blade and aesthetics modifications are the conclusion of this research. Finally, the results of optimizing and modification processes will be used to design vertical axis wind turbine for BTS tower.
