MULTIPLE-USE TWO-WAY FLUID FLOW TURBINE

摘要

Novelty: a multiple-use two-way fluid flow turbine is disclosed. Constitution: the proposed arrangement is composed of an horizontal-axle turbine bearing lengthwise adhered semi-cylindrical blades and bearing a double hydrofoil (one for each fluid current direction) driving the flow to the hollow surface of the semi-cylindrical blades while isolating the curved surface of these last; a pair of sub-marine walls enclosing the turbines is susceptible to increase the kinetic energy of the water thanks to the funnel-shaped configuration formed at the ends of said walls. Turbines without hydrofoils but covered up to their axle by aerodynamic airfoils can be placed on aircraft wings and in hybrid or other vehicles as well. Turbine with a single hydrofoil can be placed in rivers, waterfalls or behind dams. Advantages: compared to so far used tidal power generation engines, the invented turbine exhibits low installation and maintenance cost; it has low vertical height what leads to the multiplication of the places offered for installation (installation even between lighting columns); low environmental consequences and a plethora of potential installations in the north and south Evoikos gulf. Purpose: to resolve energy problems in Greece and create energy excess for exportation.
