Weakly nonlinear modeling of submerged wave energy converters

摘要

Wave-to-Wire numerical models being developed for the study of wave energy converters usually make use of linear potential flow theory [1-5] to describe wave-structure interaction. This theory is highly efficient from a computational perspective. However, it relies on assumptions of small wave steepness and small amplitude of motion around mean positions. Often, maximization of wave energy converters' energy performance implies large amplitude motion [6-8], thus contradicting the assumption of small amplitude motion.
