Abstract

Wave energy is very abundant in the oceans. Backward bent duct buoy (BBDB) is a type of wave energy converter with a relatively high efficiency and reliability. The researchers are trying to promote its efficiency and reliability by varying its shape. In this paper, a 3D numerical and parameterized model of a novel and freely-floating BBDB with convex bottom like a boat was constructed. The convex bottom is designed to capture more wave energy and to improve the navigability. The numerical simulation was implemented on self-made code. Using this model, the device hull and water column's motions and their influence on the capture width ratio η, and the structure parameters and pneumatic damping's influence on the η and peak periods were investigated and analyzed. Besides, the methods to promote η by reasonably setting these parameters' values were proposed, and the method to improve the device's η bandwidth was also found. This paper offers some guidelines for the improvement of wave energy converter's performance.
