Abstract
The wind wall is a solid structure composed of modular wind cells; the joint between two adjoining wind cells, seen from a cross-section that passes parallel through the axes of axial symmetry of both wind cells, include a shape of a complete airfoil, and both wind cells are arranged sharing a same chord; where this chord is contained by the adjacent outer section of both wind cells. It is an aerodynamic structure specially designed to increase the wind speed within a critical space and, therefore, increase the wind power available to be used by the rotor of a wind turbine.

A Wind Wall, comprising:
- a plurality of Wind Cells (104), where the Wind Cells are arranged adjacent to each other, compounding as a whole a continuous structure;
- where the Wind Cells are modular;
- wherein each Wind Cell has an individual structure, functional in itself, through which the wind passes from a wind inlet opening (406) placed on one side of the Wind Cell, to a wind outlet opening (407) placed on the opposite side of said Wind Cell;
- wherein the wind inlet opening (406) and the wind outlet opening (407) are communicated and have the very same dimensions;
- wherein each Wind Cell comprises an internal aerodynamic chamber (501) in its interior with a shape of a revolutionized extrados (upper face) of an airfoil, where the shape of the revolutionized extrados is obtained by rotating an extrados around the axis of symmetry of the Wind Cell;
- wherein each Wind Cell comprises an adjacent outer section (404) formed by the outer walls of the Wind Cell;
- wherein the revolutionized extrados (upper face) of the airfoil of the internal aerodynamic chamber (501) consists of a profile of a double hyperboloid truncated and joined at the origin, taking into account that the double hyperboloid profile comprises an inlet hyperboloid (506) facing the wind direction, disposed adjacent and perpendicular to the wind inlet opening (406), and an outlet hyperboloid (507) not facing the wind direction, placed adjacent and perpendicular to the wind outlet opening (407);
- wherein the geometric shapes of the inlet hyperboloid (506) and the outlet hyperboloid (507) of the same Wind Cell are different from each other, with a magnitude or internal volume of the inlet hyperboloid (506) being smaller than the magnitude or internal volume of the outlet hyperboloid (507);
- the joint between two adjoining Wind Cells, seen from a cross-section that passes parallel through the axis of symmetry of both Wind Cells, exhibits a shape of a complete airfoil, and both Wind Cells are arranged as sharing a same chord;
- where this chord is contained by the adjacent outer section (404) of both Wind Cells;
- and,
- wherein the inlet hyperboloid (506) and the outlet hyperboloid (507) are both a one-sheet hyperboloid truncated and joined at the origin by identical circles in such a way that the connection between both geometric figures is continuous, that is, that the inlet hyperboloid (506) and the outlet hyperboloid (507) together form a continuous geometric figure with axial revolution symmetry.
