锥形中心管浮标试验研究

BUOY EXPERIMENT OF CON-SHAPED CENTER-PIPE

该文研究了中心管结构对能量转化性能的影响,并得出提高波浪能俘获性能的若干方法。设计了3个不同直径的中心管模型进行试验。且进一步研究了锚系位置和喷嘴比对模型俘获性能的影响。试验结果表明,中心管面积占底面面积的比例与模型最高俘获宽度比有直接关系。锚链系于浮仓底部相对于其他位置,能使模型更加稳定,俘获效果更好。中心管最高俘获宽度比对应的喷嘴比为2%,且随着喷嘴比增大,通频带变宽。

The paper study the influence of the oscillating center pipe structure on the energy conversion performance,and obtain some methods to improve the wave energy capture performance.Design and test three models of center pipe with various diameters.Furthermore,the effects of anchor position and nozzle ratio on the capture performance of the model are studied.The experimental results show that the ratio of the center tube area to the base area is directly related to the maximum capture width ratio of the model.The anchor chain is attached to the bottom of the tank,which can make the model more stable and capture effect better.The capture width ratio is maximum when the nozzle area ratio is 2%,and the pass-band widens with the increase of the nozzle ratio.
