Abstract
RETRACTED PAPER: Energy conversion from ocean waves has become the need of the hour in view of the renewable energy awakening occurring all over the world. Energy conversion by Oscillating Water Column (OWC) concept has become an established technology in converting mechanical energy of ocean waves to electrical energy. But the limitations of OWC concept calls for further research and developments to make the technology commercially an attractive one. In this context Boccotti, the Italian scientist advanced the double chamber concept and the implications of the concept still remains to be investigated through model studies. This paper presents the details of a generic study carried out in a physical model device under regular waves.
Highlights
Nations feel compelled to advance the concept of clean energy production from renewable energy sources
Wave energy conversion philosophies emerged over the period of time out of both scientific and speculative intuitions are so diversified that it is very difficult to bring them under a unified conceptual design procedure
The first patent historians recorded in the eighteenth century [2] for the conversion of wave energy in to mechanical energy by a father and son attests man’s ocean energy awakening and his attempts for its utilisation in meeting the daily energy needs
Summary
The environmental problems being generated out of fossil fuel usage have become an issue for. The results presented showed that the power absorption capacity of the device depends on mouth opening elevation, wave length and direction of the incident wave This brings out the fact OWC system response is determined by the magnitude of the dynamic pressure and its excitation period. By theoretical calculations it was predicted that the device was capable of absorbing the incident wave energy up to 100% This concept offers flexibility in design to bring forth tuning effect in energy conversion by capturing the maximum pressure intensity under the waves. E here are energy conversion efficiency (λ) inside the air chamber and phase difference (φ ) between incident pressure and wave pressure. It is obtained from the maximum value of cross correlation between the two time series
