Development of a Multi-Water-Chamber Type Seawall for Effective Wave Power Extraction and Wave Dissipation

摘要

The energy of ocean waves can be exploited to meet energy demands.Various devices have been developed to extract ocean wave energy.The present paper investigates multi-water-chamber seawalls that canextract wave power. The wave power is extracted using a Savoniuswater turbine and guide vanes that increase the efficiency of extraction.The application of a multi-water-chamber seawall is also intended toreduce the reflection of waves. Results show that the maximum waveenergy conversion efficiency is about 20% and the reflectioncoefficient of the multi-water-chamber seawall is about 0.3 on average.
