Abstract

The present study examines the dimensional effects on the performance of the Wave Line Magnet (WLM) wave energy converter (WEC). A potential-flow framework was employed, using the boundary element method implemented in ANSYS-AQWA software. This research aimed to determine how modifications in the WLM's geometry influence power generation while maintaining a constant overall mass. Various environmental conditions were analyzed. The frequency-domain analysis included added mass, radiation damping, as well as diffraction and Froude–Krylov forces, while the time-domain simulations were used to evaluate the optimum damping coefficient, maximum extractable power, and capture width ratio. The results indicate that increasing the platform length, under constant mass, enhances the mean power output by more than 91% from the smallest to the largest examined platform configuration length. Similarly, increasing the major diameter of the elliptical platform cross-section leads to significant performance improvements, with the largest major diameter producing approximately 82% more power than the smallest configuration. These findings highlight the strong geometric sensitivity of the WLM and provide useful guidance for its future optimization and scaling.
