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
