后向弯曲导管浮标（BBDB）是增田发明的一种振荡水柱波能转换器。据说BBDB具有上级初级转换效率，同时保持较小的系泊成本。然而，除了初级转换效率与其运动的关系外，体型与其运动之间的关系还存在一些问题。本文对五种不同的BBDB模型进行了大量的物理试验。从实验结果中，得到了BBDB船体形状和初级转换效率的影响。此外，还提出了获取入射波分量的方法和利用BBDB的实验结果获取BBDB在入射波下的响应的方法。
Backward Bent Duct Buoy (BBDB) is a type of oscillating water column (OWC) wave energy converter invented by Masuda. BBDB is said to have superior primary conversion efficiency with maintaining small mooring costs. However, some problems remain unclear with the relationship between body shape and its motions in addition to the primary conversion efficiency and its motions. A number of physical tests for five different BBDB models were carried out in this research. From these experimental results, the effects of BBDB hull shape and the primary conversion efficiency were obtained. Furthermore, methods for obtaining incident wave components and for obtaining the responses of BBDB induced by the incident waves using the experimental results of BBDB are proposed.
