- Figure 1 shows an embodiment of an individual vertical turbine assembly 1 which is mounted with its base 2 rigidly connected to a support column 17.
- the turbine rotor 3 of rotor swept area diameter *D', with air foil rotor blades, is attached via a central rotating shaft 16 to power generating equipment within the non rotating hub 4 which is supported by a column 5 extending from the base 2 of the complete assembly.
- the rotor 3 is a horizontal axis type rotor mounted with its axis vertical.
- the hub contains the electrical power generator 15a and all associated equipment for converting the rotor's rotational torque into electrical power.
- Vertical walls 6 arranged radially, extend in an angle to the vertical from the base 2 of the shroud to the bell mouth entry of the shroud. Radially they span from, near the central air chamber's perimeter 12 to beyond the
- a conical section 37 extends from the last toroid' s trailing edge 49 to meet the support column 5, to completely enclose the last toroid' s annulus.
- wind flowing from any direction and entering the shroud's horizontal passage ways 13a, 13b 13c, 13d and 13e created by the toroid blades 10a, 10b, 10c, 1Od and 1Oe, will accelerate and exit the blades at a higher velocity into the central collection chamber 12.
- the lowest passage 13e which is located closest to the central axis of the chamber is designed to produce the highest exit velocity and it will be directed across the face of the inactive passage ways 38 which are not directly facing the wind.
- This movement of air acts as a fluid dynamic ⁇ air gate' , due to its pressure being lower than the pressure in the entry side 39 of the inactive passage ways and induces air flow into the chamber 12 via the inactive passage ways, thus significantly reducing the escape of air entering the chamber via the active passage ways .
- the 'bell mouth' entry section toroid 7 of the shroud narrows concentrically towards the throat 8.
- the turbine rotor 3 is situated near down stream of the throat.
- the air stream profile of the rotor hub 4 and nose cone is designed to ensure that the air approaching the throat from the active passage ways is able to flow across to the far side of the throat with minimal interference. This results in the full swept area of the rotor blades receiving air at near uniform velocities across it.
- the shroud then expands as the concentric- diffuser 9 with an open top 21.
- This diffuser allows the pressure of the air leaving the turbine blades, which is below atmospheric pressure to rise steadily to near ambient pressure levels. The velocity of the air decreases as the diffuser expands.
- the diffuser extends and expands further as a collar 40 finally opening to the atmosphere 21.
- a wedge 41 is formed along the perimeter of the outer surface of the diffuser to deflect, in combination with the collar, near vertically the free stream air approaching the diffuser from the wind ward side. This deflection creates a suction effect along the internal walls of the wind ward side of the diffuser and increases air flow exiting the diffuser, resulting in increased air flow being drawn through the throat 8.
- Fig. 2 shows an embodiment of the present invention forming the wind power station with an individual omni ⁇ directional shrouded vertical wind turbine installed rotated 180 degrees about a horizontal axis ⁇ completely inverted) with a suitable support structure, such that the air discharge from the outlet of the unit is vertically downwards.
- the clear opening height 'C, in the vertical direction between the air discharge outlet and any other surface is not less than 85% of the diameter 'D' of the swept area of the rotating member of the vertical turbine. This minimizes the resistance for the air exiting the turbine after passing through the rotor.
- this minimum spacing value X C will need to be higher.
- ⁇ C shall be a minimum of 225% as otherwise the discharge air from both units will interact and reduce efficiencies.
- Fig. 3 shows embodiments of the present invention adapted for use as an omni-directional "vertical" wind power generating station which consists of multiple vertical turbines arranged vertically one above the other on a structural support co-axially (A) or staggered off-axis
- the height ⁇ T' of the spacing shall be minimum 30%, preferably between 30% and 95% of the overall height 'H' of an individual vertical turbine unit.
- This "vertical" power station configuration results in increased power generation due to the increased air flow through the individual vertical turbine unit's rotor, as a result of the increased suction across the face of the discharge out let of each individual unit in a vertical interaction zone.
- the vertical interaction zone is a zone of vertical spacing between adjacent vertical turbines which is selected so that the efficiency of the turbines is greater than the efficiency of a stand-alone free vertical turbine.
- the vertical interaction zone excludes vertical turbines spaced at less than 30% spacing.
- At less than 30% vertical spacing the air flow through individual units is throttled and power generation reduced.
- the vertical interaction zone excludes vertical turbines spaced at greater than 95% spacing. At greater than 95% vertical spacing the power enhancement effect due to acceleration of ambient air flow through the spacing is lost.
- Fig.4 shows an embodiment of the present invention adapted for use in an omni-directional "vertical" wind power generating station which consists of multiple vertical turbines arranged vertically stacked, one directly above the other, with a common central rotating shaft connecting the turbine rotors of two or more of the units to one or more electrical power generators.
- Fig. 5 shows embodiments of the present invention adapted for use in a "horizontal" omni-directional wind power generating station which consists of multiple vertical turbines arranged in a horizontal line, one next to the other at the same height (A) or staggered in height (B) with spacing between each of the individual vertical turbines.
- the spacing 'G' between the extremities of each of the vertical turbines shall be a minimum of 16%, preferably between 16% and 76% of the extreme width ⁇ W of an individual vertical turbine unit, when taken at any common horizontal plane between the two units.
- This "horizontal" power station configuration results in increased power generation due to the increased air flow through the individual vertical turbine unit's rotor, due to reduced by passing of air around individual units in a horizontal interaction zone.
- the horizontal interaction zone is a zone of horizontal spacing between adjacent vertical turbines which is selected so that the efficiency of the turbines is greater than the efficiency of a standalone free vertical turbine.
- the preferred horizontal interaction zone excludes vertical turbines spaced at less than 16% spacing. Below this spacing the total air approaching the complete power station is reduced, resulting in power loss.
- the preferred horizontal interaction zone excludes vertical turbines spaced at greater than 76% spacing. At greater than this spacing the power enhancement effect due to interaction of air flow by-passing the units is reduced progressively and lost.
- any or all of the individual vertical turbines may be arranged in the normal (up right) configuration or in the 180 degree rotated (inverted) configuration as shown in Fig.6.

- Each of the individual omni-directional, shrouded vertical discharge wind turbines utilized consists of an axial, aerofoil type rotor placed within a shroud.
- the open design of the shroud with minimal constriction in comparison with other vertical discharge shroud arrangements, the aerodynamic focusing, accelerating arrangements, the fluid dynamic w air gate" arrangement to prevent leakage and the wedge/collar arrangement at the discharge of the diff ⁇ ser to increase suction effects through the shroud promotes much higher air volumes to flow through the rotor.
- the power extracted by the rotor is transferred to an electric power generator through a rotating shaft mechanism.
- the slender profile of an embodiment of the vertical wind power station allows accommodation of it in single or multiple numbers in either open areas in the country side or in narrower street ways within suburban areas.
- the choice of materials for the individual omnidirectional, shrouded vertical wind turbine's vertical walls, diffuser and toroidal blades will be among strong, light weight metals, composites, sandwich construction etc.
