  1. School of Civil and Environmental Engineering HARNESSING WAVE ENERGY BY DOUBLE CHAMBER OSCILLATING WATER COLUMN DEVICE Periods of rapid development in technological and economic activities of nations has increased the enormous consumption of fossil fuels and the subsequent manifestation of irreversible changes observed in the ecosystem has compelled mankind to think of sustainable development in all phases of human activities. This has generated renewable energy awakening all over the world. In the present time, it has become a historic opportunity before the coastal nations to extract energy available in the ocean waves for the energy needs of the society. In this presentation, attempts have been made to project relative merits of a new conceptual design (Double Chamber Oscillating Water Column) tested for conversion of wave energy in to pneumatic energy at Ocean Engineering Department, IIT Madras, India. The other aspects being focused are: the fundamentals in ocean wave hydrodynamics which can cause paradigm shift in innovation approaches in energy converters, a brief overview on wave energy conversion principles and the history of the incremental steps taken in wave energy converter technology development. The hydrodynamic performance of the device observed under varying wave periods and wave heights are presented and the future scope for further research in optimization process is explained. Prof. Vallam Sundar Vallam Sundar is a professor of Department of Ocean Engineering, Indian Institute of Technology Madras, Chennai, India. He served as the Chairman, Asia Pacific Division of Intl. Assoc. of Hydraulic Engg. Research, during May 2007-Dec 2011. He is also a Member of European Union for Coastal Conservation.His primary research interests are on the experimental studies of the interaction of ocean waves with coastal and offshore structures. He has undertaken more than 200 research projects and published more than 400 academic papers in domestic and international conference and journals. Vallam Sundar was awarded by Indian Publishing House, New Delhi as "Best Citizen of India Award" for the year 1998. In total, he received nine awards including the Honorary doctoral Engineer award Univ. of Wuppertal, GERMANY (2006) and "Maritime Award" by Ministry of Shipping Road transport, Ministry of Shipping, Govt. of India for the research paper titled "Tsunami wave interaction with NDBP data buoy", for the year 2005-2006.
