Performance Studies on a Scaled Model of Backward Bent Ducted Buoy (BBDB) Type Wave Energy Converter in Regular and Random Waves

摘要

The National Institute of Ocean Technology (NIOT), in cooperation with IIT-Madras is actively engaged in research and development of ocean energy resources. As a part of the continuing research on wave energy converters and power systems, NIOT initiated a joint research project on floating Backward Bent Ducted Buoy converters, in collaboration with the Pacific Society, Japan. Using the model test results conducted elsewhere, a smaller model suitable for testing in the wave tank facility at IIT-Madras was designed. A number of parameters such as the pressure developed inside the device, the elevation inside the chamber, the pneumatic power that can be extracted and the average wave to pneumatic power conversion efficiency in real seas have been measured. This paper discusses the performance of a BBDB device under regular and random wave conditions.
