A contra-rotating turbine system is theoretically torque free, since the second blade counters the first blade torque. In this study the contra-rotating turbines are adopted as an ocean current power generator. In this paper computational study is performed to investigate the wake flow characteristics of contra-rotating configuration. In additional to calculating the hydrodynamic forces and power outputs by using Computational Fluid Dynamics (ANSYS Fluent 18.0).

In this study the flow generated by the ocean current turbine has been calculated. The purpose is to study how a contra-rotating ocean current turbine design. This method is validated by comparing with experimental results.
