Use of a Rectangular Liquid-Filled Bottom-Mounted Distensible Device to Harness Nearshore Wave Power

摘要

The present work aims to find out the applicability of the bulge concept used in the Anaconda (Chaplin et al., 2011) on a possible seabed version. The tested model is a long rectangular duct covered with an elastic membrane and placed on the seabed, parallel to wave propagation. The tension in the membrane and its submergence can be varied by pressurising the system. Two configurations were tested: one with closed ends and one with a Power Take-Off system. Measurements were made of pressure in the duct, membrane displacement and capture width and are compared with a theoretical 1D model.
