EXPLORING THE IMPACT OF DUAL ORIFICE AIR COLUMN ORIENTATIONS ON THE PRIMARY CONVERSION EFFICIENCY OF BACKWARD BENT DUCT BUOY (BBDB)

Abstract

This research investigates the Backward Bent Duct Buoy (BBDB), a floating type of Oscillating Water Column (OWC), focus on assessing the influence of dual orifice air column orientations on its primary conversion efficiency. The study includes the design and fabrication process of the top panel, conducted through SolidWorks CAD software and laser cutting methods using acrylic sheets as materials. Notably, Configuration 1 demonstrates the highest efficiency at 0.092%, followed by Configuration 2 at 0.091%, and Configuration 3 at 0.083%. These findings contribute to understanding the performance differences of BBDB configurations, offering understanding for further advancements in wave energy conversion systems .
