Numerical study of contra-rotating Vertical Axis Wind Turbine H-Rotor Darrieus type / Aditya Ilham Setyawan Haryogo, Vivien S. Djanali and Bagus Nugroho

The new Contra-rotating Darrieus turbine configuration has been invented to enhance the Vertical Axis Wind Turbine (VAWT) performance. This configuration increases the relative rotational speed of the generator, resulting in higher output power. It is well known that the increase can reach four time...
