Numerical analysis explores wave energy harvesting performance in floating structures, suggesting effective motion suppression.
Key Points
The research investigates the effectiveness of dual oscillating water column devices for energy harvesting and motion mitigation in floating structures.
Numerically analyzed using OpenFOAM and waves2Foam.
Applied volume of fluid method for interface capturing.
Utilized six-degree-of-freedom dynamic mesh solver waveDyFoam for motion response analysis.
Evaluated influence of chamber width, wall draft depth, and PTO settings on performance.
Achieved optimal pitch motion suppression with specific chamber width, wall depth, and PTO settings, reducing amplitudes by over 63%.
Found that energy conversion efficiency is sensitive to PTO parameters, with an optimal configuration at e = 0.5%.
Larger chamber widths and smaller wall depths enhance energy conversion efficiency and bandwidth.
