Abstract:
Tidal energy is one of the cheapest energy that we find naturally like wind energy & solar energy. The source of this energy is water tide. Tidal energy conversion techniques exploit the natural rise and fall of the level of the oceans caused principally by the interaction of the gravitational fields in the planetary system of the Earth, the Sun and the Moon. The main periods of these tides are diurnal at about 24 h and semidiurnal at about 12 h 25 min. A tidal turbine is a device for extracting energy from marine currents, and functions in a manner similar like wind turbine. There are different types of tidal turbine basically they are classified based on their turbine blade orientation. Some of them are called horizontal axis, vertical axis, helical horizontal axis, and helical vertical axis tidal turbine. Turbine shaft is connected with the generator. A generator mainly produce power, changing the kinetic energy of current into a turning force by setting a water turbine in the direction of tidal current. Because of the massive size of the oceans and the prediction accuracy of tidal, it is more preferable than any other renewable sources. While the discussion in this paper focuses mainly on Sandwip, Khepupara and Hiron point. The messages are relevant for other areas that have the potential to engage in Tidal Power. So the main objective of our project is to find which one is best for harnessing potential energy among these three areas.
Description:
First of all, praise is due to almighty ALLAH with his compassion and mercifulness to allow us finalizing this undergraduate thesis. We express sincerest gratitude to our supervisor, Prof Dr. Muhammed Mahbubur Razzaque, Dept. of Mechanical Engineering, Bangladesh University of Engineering & Technology (BUET), Dhaka 1000, Bangladesh, who has supported us throughout our thesis with his patience and knowledge. We attribute the level of our Bachelor degree to his encouragement and effort and without him this thesis would not have been completed and written.
We are grateful to MIST for funding. It would not be possible to complete this thesis without the financial co-operation of this organization. Finally, we thank our parents for supporting us throughout all our studies at University. We are also grateful to different persons who helps us in different stages of the thesis work.
