Abstract

This study introduces the Wave Line Magnet (WLM), a novel wave energy converter designed as an array of floating platforms that captures ocean wave motion to generate renewable energy, offering a viable solution for sustainable power generation. The WLM's performance is evaluated using the ANSYS-AQWA program, which employs the Boundary Element Method and accounts for hydrodynamic interactions among the platforms. The governing equations are based on potential flow theory, and experimental data with a similar movement mechanism is used to validate the numerical results, focusing on position and angular velocity. The research highlights the effects of environmental conditions and the number of oscillating components on WLM performance. Wave characteristics, such as period and height, are analyzed concerning the maximum power output produced by the optimal damping coefficient, with a maximum generation of about 2.5 MW. The WLM shows non-linear behavior, efficiently extracting energy from wave periods of 4–13 s, with power output increasing by up to 200 % when wave height doubles. Although adding more oscillating components does not always guarantee higher power output, evidence suggests that power generation generally increases with more platforms. The study also emphasizes optimizing damping coefficients, which vary nonlinearly with wave height and period; for example, at a wave height of 3 m, the damping coefficient decreases from 545,000 radians/second at a 4-s period to 308,000 radians/second at a 13-s period. Additionally, longer wave periods do not necessarily result in increased power output, despite higher wave heights improving energy capture.
