ABSTRACT
Thephenomenon of rise and fall in the ocean waters, called tides, is due to the attractive forces between the celestial bodies; Sun, Earth and the Moon. When the ocean water rises to a maximum extent, it is called spring tide and when they fall off to the lowest possible extent, it is called neap tide. With progress in technology, the usage of electric and electronic devices is exponentially increasing and there is a need to produce extra power other than the existing, in order to meet the future demands. Tidal energy can be considered as one of the best existing source of renewable energies Unlike the wind, solar, thermal energy etc., tidal energy is something that has a long term perspective and it can be forecasted more accurately. Tidal energy is clean and not depleting. Because of these features it is unique and suitable to use it as a power generating source in the future. There are various types of tidal power plants across the world with varying tidal elevation. Also, the method of conversion of tidal energy into electrical energy is site specific. But generally, the method followed for extracting energy from tides is similar to the conventional hydroelectric power plants. In this paper, the tides at some locations across the world and along the Indian coast, tidal power plants across the world, resource allocation of tidal power plants, advantages and disadvantages of tidal. The study consists of measuring theoretical energy creation if a mechanism were to be placed in the sea flow below tidal areas. Tidal loading causes fluid to move within the sea floor, this theoretically can be made into electricity, by means of turbines. They considered the gas flow as well as simple fluid flow, and give expressions to find calculated energy creations. Though this energy may not be able to be obtained all of the time, only favorable conditions will be able to create enough electricity. Base on current understandings, tidally induced flow in subsea formations appears to make little.
ACKNOWLEDGEMENT I wish to record my deep sense of gratitude and profound thanks to my faculty Mr.P.Manuneethi Arasu, assistant professor, mechanical engineering,
k.s.r college of engineering, tiruchengode, for his keen
interest, inspiring guidance, constant encouragement with my work during all stages, to bring this thesis into fruition. I am extremely indebted to Dr. Sivashankaran, head of the department,
mechanical engineering, k.s.r college of engineering,
tiruchengode, for their valuable suggestions and support during the course of my research work. I also thank the faculty and non-teaching staff members of the mechanical engineering, k.s.r college of engineering, tiruchengode, for their valuable support throughout the course of my report work.
