摘　　要：针对现有波浪能技术存在成本高、生存性差等问题,本文研究一种具有航行潜质的变体水柱波浪能转换系统,它由浮力舱、垂直管、水平管、闸门等组成,通过闸门改变振荡水柱的长度和形状,改变航行阻力,实验研究了水柱的长度和形状变化、气流做功方式对系统转换特性的影响,并提出一套量化标准对系统的转换特性进行评价。水槽实验表明:模型规则波下最高俘获宽度比达到了154.6%,随机波下最高俘获宽度比达到了97.0%;规则下闸门打开的模型的俘获宽度比大概是闸门关闭模型俘获宽度比的1/2,随机波下闸门打开模型的俘获宽度比大概是闸门关闭模型俘获宽度比的3/4。Aiming at the problems of existing wave energy technology,such as high cost and poor survivability,this paper introduces a new wave-energy converter with a variable water column for propelled capability.This converter consists of a buoyancy tank,vertical pipe,horizontal pipe,and sluice gate,among others.By opening and closing the sluice gate,the length and shape of the water column in the converter are changed,resulting in a change in the motion resistance.The effects of the changes in the length and shape of the water column and the way of airflow work on the conversion characteristics of the system are studied experimentally,and a set of quantitative criteria is proposed to evaluate the conversion characteristics of the converter.The results of flume experiments show that the maximum capture width ratio reaches 154.6%for regular waves and 97.0%for random waves.The capture width ratio of the gate-opening converter is about 1/2 that of the gate-closing converter under regular waves and about 1/2 under random waves.
