Abstract
Multi-body wave energy converter is being considered to be one of harvest technologies to maximize the potential to extract the renewable source of energy from the ocean. The key issues in this field are to understand the interaction between bodies; and develop the awareness of how to utilize the impact of these. This paper describes a set of numerical simulations designed to investigate the optimum configuration of a simple two-body point absorber device. Deep-water condition is applied and regular surface waves are used to describe the ocean waves. The single point-absorber system is modeled as two independently moving bodies connected to a direct driven linear generator and the generator is simplified as a spring-damping system. The results confirm that the ability to extract energy depends on the mass and geometry of the moving parts, together with the damping of generator. It is also demonstrated that the outcome is sensitive to the distance between the two moving bodies and local wave condition
