摘要
后弯管(BBDB)技术从波浪能到电能的转换要经过多个环节,为提高后弯管技术能量转换性能,对一种新型的后弯管技术多环节阻尼形式展开了实验研究。水槽实验研究表明,在气流单向做功条件下,规则波下俘获宽度比(CWR)峰值为113.7%,随机波下CWR峰值为81.9%,而在气流双向做功时,规则波下CWR峰值为138.6%,随机波下CWR峰值为94.0%;相对于简单气孔阻尼模型,带有导叶、叶轮和发电机元件阻尼的试验模型的CWR稍高于简单纯气孔模型,两者CWR曲线变化的趋势接近。
The conversion from wave energy to electric energy in backward bent duct buoy(BBDB)technology goes through several links.To improve the energy conversion performance of the BBDB technology,a new BBDB model was studied experimentally.From narrow wave flume tests,it was found that the peak capture width ratio(CWR)was 113.7%under regular waves and 81.9%under random waves when doing work by airflow in one direction.The peak CWR was 138.6%under regular waves and 94.0%under random waves when doing work by airflow in both directions.Compared with the simple stomatal damping,the CWR of the test model with guide vane,impeller,and generator component damping was slightly higher than that of the simple pure stomatal damping,and the variations of the CWR curves of the two damping were almost the same.
