- Study on Interference Effects of Upstream and Downstream Rotor of Contra-Rotating Ocean Current Turbine
抄録
<p>The environmental problem and related energy problem are recently the serious problem all over the world. The possible use of ocean current as an energy resource begins to draw attention in the renewable energy. In this study the contra-rotating turbines are adopted as an ocean current power generator. Firstly, single rotor horizontal axis ocean current turbine performance estimated by Computational Fluid Dynamics (CFD) is carried out. Predicted results show good agreements with experimental results. Next, the water tank test to investigate the influence of upstream and downstream turbine aerodynamic interaction is performed. The downstream turbine rotation speed is 25 % slower than upstream turbine. Finally, wake flow distributions are evaluated by the CFD analysis of contra-rotating turbine using the result of the water tank test. Faster wake recovery behind contra-rotating turbine is confirmed from the calculated results.</p>
