Abstract:

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 pitch motion, so, a pendulum is designed for transferring this motion to the PTO. In this paper, the WEC is evaluated for a wide range of waves in the wave tank. The wave characteristics are presented by which the system had appropriate pitch motion and acceptable extracted electrical energy.

EXPERIMENTAL INVESTIGATION OF OFFSHORE WAVE BUOY PERFORMANCE

The important characteristic of sea waves is their high energy density, which is the highest among renewable energy sources. Having up to 2700 km. of shoreline, Iran has a great potential in construction of offshore wave buoys (hereafter called OWB). In this article a OWB model with the possibility of assembling different buoy configurations is introduced. The system is exposed to regular and i...

Development of a mathematical model to design an offshore wind and wave hybrid energy system

Fossil Fuels are always considered as environmental pollutants. On the other hand, the political and economic situations highly affect the price of these fuels. Offshore wind and wave, as renewable energy sources, represent the better alternatives for electricity generation. Therefore, it is necessary that wind speeds effectively be estimated due to the absence of field measurements of the wind...

Experimental Update of the Overtopping Model Used for the Wave Dragon Wave Energy Converter

An overtopping model specifically suited for Wave Dragon is needed in order to improve the reliability of its performance estimates. The model shall be comprehensive of all relevant physical processes that affect overtopping and flexible to adapt to any local conditions and device configuration. An experimental investigation is carried out to update an existing formulation suited for 2D draft-l...

Interactions Between an Oscillating Wave Surge Converter and a Heaving Wave Energy Converter

In this paper, we investigate the mutual hydrodynamic interactions between two different kinds of devices, namely, an Oscillating Wave Surge Converter modeled as an oscillating flap and a generic Heaving Wave Energy Converter modeled as a vertical truncated cylinder. A three-dimensional mathematical model based on linear potential flow theory is developed. It is assumed that the effects of the ...

Extreme Wave Loading on Offshore Wave Energy Devices using CFD

Two commercial Navier-Stokes solvers are applied to wave-wave and wave-structure interaction problems leading to the final application of simulating a single float of the wave energy converter (WEC) Manchester Bobber in extreme waves and a fixed section of the Pelamis in regular waves. First the two software packages CFX and STAR CCM+ are validated against measured results from physical tank te...

Wave Energy Converter through Piezoelectric Polymers

This note addresses the concept of wave energy conversion by means of piezoelectric material. The ocean surface waves represent an important source of energy power. A multiphysics simulation is used to focus on different aspects, namely the free surface wave, the fluid-structure-interactio, the mechanical energy input to the piezoelectric material and finally the electric power output using an ...
