Description:BACKGROUND
Field of the invention
[001] Embodiments of the present invention generally relate to turbines and particularly to a double stage vertical axis twin blade turbine.
Description of Related Art
[002] Various sites are present in estuaries, on rivers, and so forth where a substantial energy can be extracted from flowing water. Therefore, water turbines have been designed for extraction of the energy from the flowing water. However, such water turbines were operated at a very low-pressure head. To overcome the aforementioned issues, various water turbines with high pressure head have been designed.
[003] Conventionally, the available water turbines are easy to construct due to their simple design, however, they have low performance metrics. Moreover, the available water turbines are having a high initial operational cost and less efficient. In addition, the water turbines are difficult to fabricate as the water turbines require robust parts that can resist water pressure with high kinetic energy for a number of years. In some of the prior art references, a turbine is usually built with one blade which is easy to fabricate but does not take full advantage of torque produced by the kinetic energy of fluid.
[004] There is thus a need for an improved and advanced turbine that can administer the aforementioned issues in a more efficient manner.
