Research on Hydrodynamics and Energy Capture of Sea Snake Wave Energy Generation Device

本文基于三维势流理论,首先利用SolidWorks软件进行海蛇式波浪能发电装置的建模并计算装置的质量属性。其次利用AQWA水动力计算商业软件对该发电装置不同浪向下横摇、纵摇和艏摇位移响应做频域分析。结果表明,该海蛇式波浪能发电装置在不同浪向下纵摇响应均较大,尤其是迎浪状态时响应最为剧烈。同时,本文还研究了该发电装置在0°浪向下的纵摇响应,结果表明,装置适宜布置在波浪周期常年位于4~13 s范围的海域。最后,本文还基于中国沿海地区选取三种常见海况对装置进行不规则波海况模拟,结果表明,在三种不同海况下装置均能稳定运行,将波浪能转化为电能。

Based on the three-dimensional potential flow theory,SolidWorks software is used to model the sea snake wave energy generating device and calculate the quality attributes of the device.Secondly,we use AQWA hydrody⁃namic calculation commercial software to do frequency domain analysis on the response of the power generation de⁃vice to the roll,pitch and yaw of different waves.The results show that the sea snake wave energy power generation de⁃vice has relatively better response to the pitch of different waves.The response is strongest especially in the headingup state.At the same time,we also studied the pitch response of the power generation device when the wave is 0 de⁃gree,and the results show that the device is suitable to be arranged in the sea area where the wave is from 4 s to 13 s all year round.Finally,this paper also selects three common sea conditions in coastal areas of China to simulate the ir⁃regular wave and sea state of the device.The results show that the device can operate stably to convert wave energy in⁃to electric energy under the three different sea conditions.
