摘　　要：后弯管式波力发电装置作为一种漂浮式振荡水柱式装置,具有可靠性强、安装维护方便、工作地点灵活的特点。本文在前人研究基础上,以10kW级后弯管式漂浮型发电装置为研究对象,以装置的水动力学性能为主要研究内容,以气室内相对波高作为主要表征参数,通过断面水槽水工物理模型试验,考察了气室内水柱振荡幅度与入射波波高和入射波周期之间的关系,分析了气室完全开敞、输气管添加负载以及弯管横管长度对气室内水柱振荡的影响,为进一步的大功率装置设计与试验提供了理论依据。As one of offshore, oscillating water column wave energy converters, Backward Bend Duet Buoy （BBDB） Wave Energy Converter has the significant advantages within the characteristics of reliability, adaptability, convenience for installation ＆ maintenance. Based on the former studies, the paper aimed at 10 kW-level floating BBDB devices, and took the hydrodynamics of the device as the primary investigating contents. The Relative wave heights in the chamber was regarded as the characteristics parameter. Physical model tests in the flume were carried out to investigate the relationships between wave elevations insider the chamber and incident wave conditions （heights ＆ periods）. Effects of chamber openness, loads in the duct and extending length of the chamber on the variation of relative wave heights were analyzed, which would provide more supports for design and tests of high capacity installation BBDB devices.
