Calculations of power from cylindrical buoys with different submersion levels
Abstract
This study investigates the effect of varying submersion levels on the vertical power take-off (PTO) performance of a cylindrical wave energy converter (WEC). Using a coupled force-displacement model, the research simulates different added masses to analyze their impact on oscillation dynamics and power output. Results show that while full submersion with maximum mass yields the highest instantaneous power, an intermediate added mass provides the most stable and efficient energy conversion. These findings highlight the importance of optimizing submersion depth and added mass for reliable WEC performance.
