Abstract: The aim of this study is to investigate the performance of an innovative vertical axis turbine which possesses the blade-self-deflection function for ocean current and tidal energy application. The blade deflection is accomplished by interaction of blades and related mechanisms as the turbine rotates. To enhance the turbine performance, it is designed that the blade deflection not only increases the power output for a downstream blade, but also decreases the resistance for an upstream blade. The observation of the prototype in laboratory flume is displayed to validate the feasibility. Furthermore, a commercial code is employed to analyze the turbine performance. The velocity and pressure contours of the calculation domain are simulated to obtain the torque and power output of deflectable-blade turbine. Moreover, the results of performance analysis are validated by the experimental data.
