摘　　要：为了探索中心管振荡水柱式波浪能装置的结构外形对其性能的影响,本文进行了装置外形结构设计,通过入射波要素、浮筒吃水深度、尾管高度、水下结构比例等类型的多种工况的物理模型试验,验证不同参数对装置性能的影响。试验结果表明:设计的模型对入射波周期变化敏感,对特定入射波高响应较优越,且在波高为65 mm,周期为1.1 s时,获得最大俘获宽度比为67.64%;模型浮筒吃水深度越大,则俘获宽度比越小,通频带越窄;锥形尾管高度值对模型的俘获宽度比和通频带宽影响较小;不同水下结构比例的模型之间俘获宽度比数值差距较小,比例为0.3时,模型的俘获宽度比通频带最宽。模型试验结果对装置的进一步优化具有理论指导意义。To explore the influence of the structure shape of the center tube oscillating water column wave energy device on its performance,this paper presents the external structure of this device and verifies the influence of different parameters on device performance through physical model tests of operating conditions such as incident wave elements,float draft depth,tailpipe height,and underwater structure ratio.The experimental results show that the designed model is sensitive to periodic changes in the incident wave and has a superior response to specific incident wave heights,achieving a maximum capture width ratio of 67.64%at a wave height of 65 mm and a period of 1.1 s;the larger the draft depth of the model buoy,the smaller the capture width ratio and the narrower the passband;the height value of the conical tailpipe has little effect on the capture width ratio and passband of the model,and the difference in capture width ratio values between models with different underwater structure ratios is small.When this ratio is 0.3,the capture width of the model is wider than the passband.The results of the model experiment have important theoretical guidance for further device optimization.
