Finite Element Analysis (FEA) of Helical Tidal Turbine

The spiral turbine assembly can provide unidirectional rotation at ultra-high speed, lower than the multi-directional ultra low head fluid provided. The assembly consists of a series of spiral turbine units or modules arranged vertically or horizontally to harness the power of water or wind, for example. Each turbine unit or module has multiple spiral blades and an airfoil. The wind energy modules can be connected to a rotating shaft supported by a light weight on the ground of the men. Spiral turbines can also use the power of ocean waves to provide thrust for ships. In other embodiments, a cylindrical distributor is provided in the helical turbine to direct the fluid flow to the turbine blades, thus increasing efficiency and power output. In this paper, simulation analysis is performed using finite element analysis techniques with the help of Ansys to evaluate the overall performance of helical and straight blade crossflow hydroelectric turbines with linear horizontal/vertical mode and the like. The duration, diameter and hydrofoil type of each generator are assumed to be equal.
