Design and Experiment of Water Wheel Based on Wave Energy System

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。

Ocean wave energy with the hidden features of its environmental protection and sustainability, it has been more and more countries and regions concerned, and has made some achievements. For a type of axial impeller wheel ocean wave energy power supply equipment, combining with the coast wave property, the structure design, optimization and experimental validation of the impeller wheel are done. The impeller wheel is the only wave energy transform device of the axial impeller wheel ocean wave energy power supply equipment. The energy transform efficiency is an important factor influencing the power supply. According to the motion status of the buoy, combining the offshore water mark defect features, the axial force, torque, relevant outcome pressure and energy lost are acquired for various design parameters. Those data are very useful for drawing up the prototype parameters on account of statics and energy transfer efficiency.
