The Design and Optimization of the Diversion-Type Tidal Current Turbine

For the actual low velocity flow ocean condition of tidal station, in order to obtain the clean and sustainable energy more efficiently, a diversion-type tidal current turbine, which can poly water flow under low velocity condition and achieve the function of adaptive convection, was designed. This research created the 3D model of the turbine structure, and conducted mechanical analysis of the structure with finite element analysis software ANSYS to check the reliability of the structure. Finally, the frame of the turbine had been optimized to obtain the optimal size of allowable stress.
