Numerical simulation of a floating-type point absorber wave energy converter

Reynolds-Averaged Navier–Stokes simulation of the heave performance of a two-body floating-point absorber wave energy system

This paper presents a recent numerical study conducted by researchers at the National Renewable Energy Laboratory on a point absorber wave energy conversion (WEC) system using a Reynolds-averaged Navier–Stokes (RANS)-based Computational Fluid Dynamics (CFD) method. The device we studied was a two-body floating-point absorber (FPA) that operates predominantly in heave and generates energy from t...

Ps Frog: a Point-absorber Wave Energy Converter Working in a Pitch/surge Mode

In studies of wave energy, notably those made under contract to the U.K. Department of Energy, capital costs have generally been _found too high to compete with other sources It has been shown elsewhere (1) that the large structural element in these costs can be avoided by using point-absorbers reacting against an internal moving mass. This early proposal (2) suffers from the disadvantage that ...

On the Short-term Uncertainty in Performance of a Point Absorber Wave Energy Converter

INTRODUCTION Of interest, in this study, is the quantification of uncertainty in the performance of a two-body wave point absorber (Reference Model 3 or RM3), which serves as a wave energy converter (WEC). We demonstrate how simulation tools may be used to establish short-term relationships between any performance parameter of the WEC device and wave height in individual sea states. We demonstr...

Experimental Evaluation of IRWEC1, a Novel Offshore Wave Energy Converter

This paper describes the innovative offshore point-absorber wave energy converter (WEC), IRWEC1, under development by the Hydrodynamics, Acoustics and Marine propulsion Group at Babol Noshirvani University of Technology. Totally enclosed in an outer shell, with no external moving parts, IRWEC1 is completely sealed which make it a robust and trustable system. Important motion for this WEC is the...
