Abstract

<p>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).</p><p>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.</p>
