Comprehensive Study on Tidal Energy Vertical Axis Tidal Turbine-Corrosion Prevention Solution

摘要

Estuarine processes have long been important to oceanographic researcher. The closeness of estuaries to land & the diversity of physical activity found within them have stimulated interest in estuaries as individual systems. An overview of the current design practices in the field of renewable energy is presented; also paper delineates the background to the development of unique & novel techniques for power generation using the kinetic energy of tidal streams & other marine currents. Tidal stream devices have been developed as an alternative method of extracting the energy from the tides. This form of tidal power technology poses less threat to the environment & does not face the same limiting factors associated with tidal barrage schemes, therefore making it a more feasible method of electricity production. Universally the tides can be harness with tidal turbines- of which there are two main bifurcation-vertical axis & horizontal axis. In this paper only the vertical axis tidal turbine is focused. Some suggestion & corrosion prevention techniques are also discussed in this study. In addition, the progression of technological advancements tracing several decades of R&D efforts on vertical axis turbines are highlighted. The purpose of this review paper is to build up a confidence level for further study in this field in depth.
