| 摘 要： | 为解决海洋波浪能和潮流能耦合利用的问题,提升浪流发电装置的发电效率,上海海洋大学课题组设计了一种新型涵道双向泵叶轮浪流发电装置。主要对轴流泵的工作原理进行理论分析,阐述将轴流泵排水原理应用于浪流发电装置捕获浪流能的可行性,基于轴流泵叶片设计原理,设计出一种可以双向捕获浪流能的叶片。经数据仿真和水槽实验进行验证,得出涵道双向泵叶轮浪流发电装置可以在浪流流速v=0.5 m/s工况下浪即可启动,满足低流速启动要求,发电效率最高为23.7%。

| Abstract: | A new type of Wave-flow Generation Device with a ducted bidirectional pump impeller is constructed based on the design principle of the axial-flow pump. In this study, the working principle of the axial-flow pump is analyzed and the back-stepping approach is used to design the device. A comparison with data from theoretical calculations, a numerical simulation, and tank experiments relating to the device shows the power generation efficiency of the device in different working conditions. Results show that the device can be started at a flow rate of 0.5 m/s, its output power is close to rated power at a flow rate of 1.8 m/s, and its energy conversion rate is at its highest of up to 23.7% when the working flow rate is below 1.8 m/s. However, when the working flow rate exceeds 1.8 m/s, the energy conversion rate begins to decline because the increase in the tail flow field strongly increases the reversal force to the pump impeller. |
