Abstract :
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.
