摘　　要：基于后弯管装置在规则波下的试验数据,利用流线曲率法设计制造离心式透平,将其置于后弯管装置气室喷嘴口.通过试验测试,得出装备离心式透平的振荡水柱波浪能发电装置在规则波下不同负载时的工作性能.当负载为电池时,后弯管装置在入射波周期为1.4 s时工作性能最优,在入射波功率只有7.95 W的试验条件下,输出电功率为0.7168 W,整体能量转换效率为9.02%;当负载为电阻时,后弯管装置在入射波周期为1.5 s时达到最优工作状态,在入射波功率只有7.98 W的试验条件下,输出电功率为0.8653 W,整体能量转换效率为10.85%.在两种不同负载的工况下,虽然试验数据不同,但相关曲线的运动规律相似,且都在后弯管装置俘获宽度比最佳时的波周期附近达到最佳工作状态.Based on experimental data of Backward Bent Duct Buoy(BBDB)under regular waves,a centrifugal turbine is designed and manufactured by using streamline curvature method,which is placed at the nozzle mouth of the gas chamber of the BBDB.Through experimental tests,the working performance of oscillating water column wave energy power generation device equipped with this centrifugal turbine under regular wave and different loads is obtained.When the load is battery and the incident wave period is 1.4 s,the working performance of the BBDB is the best.Under experimental conditions where the incident wave power is only 7.95 W,the output electric power is 0.7168 W and the overall energy conversion efficiency is 9.02%.When the load is resistance,the BBDB reaches an optimal working state when the incident wave period is 1.5 s.In experimental conditions where the incident wave power is only 7.98 W,the output electric power is 0.8653 W and the overall energy conversion efficiency is 10.85%.Under conditions of two different loads,although experimental data are different,motion laws of correlation curves are remarkably similar,and they reach the best working state near the wave period when the capture width ratio of the BBDB is the best.
