针对一种海洋波浪能轴流式叶轮波浪能发电装置,结合我国近海波浪特点,对该装置的叶轮进行结构设计、优化选型和实验验证。该海洋波浪能轴流式叶轮波浪能发电装置以水叶轮作为唯一的波浪能转化装置,能量转化效率是影响发电的重要因素。根据浮标的运动状态,结合我国近海水纹特征,得出不同设计参数下叶轮的轴向力、扭矩、相对出口压力、能量损失系数等关键数据。这些数据为制造样机提供力学及能量转化效率方面的指导作用。
Aiming at a kind of marine wave energy axial flow impeller wave power generation device, combined with the characteristics of offshore waves in China, the structure of the impeller design, optimization and selection and experimental verification. The ocean wave energy axial flow impeller wave power generation device uses the water impeller as the only wave energy conversion device, and the energy conversion efficiency is an important factor that affects the power generation. According to the movement state of the buoy and the characteristics of the coastal watermarks in our country, the key data of the impeller such as the axial force, the torque, the relative exit pressure and the energy loss coefficient under different design parameters are obtained. These data provide guidance for manufacturing prototypes in terms of mechanics and energy conversion efficiency.
