N2 - Renewable energy is an important thing to be concerned since the rapid decrease of natural energy. Wind power is one of renewable energy which can be used to be converted into electrical energy. Darrieus-Savonius wind turbine is a tool used to convert the wind power. The combination of Savonius rotor which has self-starting ability and Darrieus rotor which has high efficiency make this hybrid wind turbine often used in urban area. This numerical study focused on Darrieus-Savonius wind turbine with Savonius rotor placed in the middle of the Darrieus rotor (type-A) and Savonius rotor placed under Darrieus rotor (type-B) at 5 m/s, 10 m/s, and 15 m/s wind velocity. Flow interaction between Savonius rotor and Darrieus rotor occurred in the type-A configuration that caused performance reduction from each rotor. It is proved by the torque generated by type-A configuration is lower than the torque generated by type-B configuration. Generally, in the low tip speed ratio, coefficient of power of type-A wind turbine is higher than the type-B wind turbine. It is caused by the swept area of type-A wind turbine is smaller than the type-B wind turbine.
