摘要

为改善中心管振荡水柱式波力发电浮标的能量转换性能，对中心管底部设计了四4种模型并在造波水槽中进行实验研究。试验结果表明，直管型中心管俘获宽度比最小，实验测得最高为4.12%，底部有一定锥度的模型会提高俘获宽度比，目前实验最高为19.25%，并出现较高的双峰值，提高了通频带，峰值周期也随锥度的不同出现了移动。试验得到的较佳模型需要进一步优化和实验，为设计适应不同海况的发电浮标提供基础数据。

Abstract

For improving the energy conversion performance of the center-pipe oscillating water column（OWC）wave power generating buoy, four models with different center-pipe bottom shapes were designed for experimental research in the wave tank. The test results are presented. showed that For the straight pipe buoy, the maximum capture width ratio is 4.12% and presents low energy conversion performance for the straight pipe buoy. For the cone pipe buoy, the capture width ratio can be improved, presents (test ratio: 19.25%) with the cone pipe buoy, which presents higher double peaks and is as high as 19.25% at current experimental. Different cone can result in different peak period. Considering the adaption of different sea conditions, further optimization and experimental validation are necessary for the tested models.To get better energy conversion performance, more optimization and experiments will be done.

Key words： wave power generating buoy; model; center-pipe; capture width ratio; wave period
