Smart System for Generating green electricity from wave energy using a laboratory model

Abstract

Wave energy converters are a promising and important technology for diversifying renewable energy sources and reducing dependence on fossil fuels. Although many converter designs have been proposed, nevertheless, buoyancy-based systems that collect wave energy using several horizontal turbines have not received much attention. 4This paper presents physical model experiment to converted wave energy to electrical power through a buoyancy-driven mechanism. The experiments were carried out in a recirculating open channel flume located at the Hydraulics Engineering Laboratory, Higher Institute of Engineering in El Shorouk City. The physical model consists of a horizontal rectangular buoy fixed with three turbines on its front and three turbines on its back. The maximum electrical power produced in full-scale tests that was obtained experimentally. The devices demonstrated the ability to produce energy at a water depth of 6.00 m, a wave height of 2.42 m, a frequency of 0.78 Hz, and wave energy equal 7181.4 Joule/m2. It was discovered that buoyancy with three horizontal turbines mechanism performed best buoyancy than three vertical turbines. These findings advance the continuous evolution of effective, economical wave energy conversion technologies.
