Analysis of the energy-capturing characteristics of floats for point absorption wave energy generators

Abstract

Article Highlights 1. The influence degree of each factor on the capture width ratio of the float is in the descending order as follows: Float shape > Float draft depth > Maximum float radius. 2. The optimum energy-capturing frequency of the float is not necessarily the resonance frequency but is affected by the added mass, radiation damping and wave force. 3. The wave force acting on the float is not the most powerful basis to judge the energy-capturing characteristics of the float.
