GIAR: Patent

The Invention can be classified as a vertical axis turbine, free or ducted.
It is an aeraulic Reaction Turbine. It is able to efficiently convert renewable energies – coming from wave motion, from river, sea and tidal currents and from wind – into mechanical energy available at the axis of the device itself, that can be transformed into electrical energy for the widest uses.

The GIAR Turbine has the characteristic that the reversal of the fluid flow does not imply the reversal of the direction of rotation of the turbine’s blades, thus offering considerable advantages in practical applications.

When the fluid gets in contact with the blades of the turbine’s rotor, it transfers to them the most part of its kinetic and pressure energy, which is transformed into mechanical energy available directly at the axis of the turbine for further applications.
The GIAR Turbine presents a central rotating core with polygonal cross-section performing the function of dividing and orienting the fluid that flows through the turbine’s rotor, so that it increases the overall Efficiency. The surfaces of the central core, which can be flat, concave or convex, together with the blades form a reduced passage section for the fluid (Venturi tube like): during the crossing, the fluid converts the pressure energy that it still possesses into kinetic energy, and that is then recovered by the blades when the fluid leaves the body of the rotor.

Since the GIAR Turbine is symmetrical, it guarantees the same levels of Efficiency also when the direction of the fluid flow is reversed.
