Physical and Mathematical Modelling of a Point Absorber Wave Energy Conversion System with Nonlinear Damping

  • Conference paper
Hydrodynamics of Ocean Wave-Energy Utilization

Summary

A point absorber type device, damped by a single-acting hydraulic cylinder, has been tested in the laboratory and modeled mathematically. The system’s efficiency was found to be equal that of systems with double-acting pumps. Response and efficiency curves are presented from both the physical and mathematical models for the case of monochromatic wave forcing.
