振荡浮子式波浪能转换装置研究

在Froude数相同的情况下，取相似因子为10，对振荡浮子式波浪能转换装置进行了模型设计，并在中国科学院广州能源研究所的造波水槽中对装置做了模型试验，试验在规则正弦波浪作用下进行，实验数据由计算机采集。实验结果显示，振荡浮子式波浪能转换装置具有与常规的振荡水柱式波浪能转换装置相当的俘获宽度比，但其总转换效率较后者高很多，建造成本较低，是一种很有发展前途的波能装置。尽管装置的可靠性有所降低，但在波能密度比较低的区域，如中国，在采取有效保护措施的条件下，装置的性能不受影响。

Investigation on the oscillating buoy wave power device

Considering the Froude number of the model and of the prototype identical, with a scale factor of 10, a model of oscillating buoy (OD) wave power device was designed and built, and a model test was carried out in a wave tank of Guangzhou Institute of Energy Conversion. In the test, the incident waves were simple harmonic, and computers collected the experimental data. The result of experimental data processing shows that the capture width ratio of the OD is nearly equal to that of an oscillating water column (OWC) wave power device, the total efficiency of the OD is much higher than that of the OWC, and the cost of the OD is lower than that of the OWC in the same dimensions. Therefore the OD is a promising wave power device, although it is at the cost of the reliability of the device. If the OD is used in China where the wave energy stream is lower, with effective protection the device could run in the most effective way.
