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.

一种新型后弯管浮筒的数值与参数化研究

波浪能在海洋中非常丰富。后弯管浮筒（BBDB）是一种效率和可靠性较高的波浪能转换器。研究人员正试图通过改变其形状来提高其效率和可靠性。本文建立了一种新型船型凸底自由漂浮BBDB的三维数值参数化模型。凸底的设计是为了捕获更多的波浪能量，提高通航性。在自制代码上进行了数值模拟。利用该模型，研究和分析了装置壳体和水柱运动对捕获宽度比η的影响，以及结构参数和气动阻尼对η和峰值周期的影响。此外，还提出了通过合理设置这些参数值来提高η值的方法，并找到了提高器件η带宽的方法。本文为提高波能转换器的性能提供了指导。
