Definitions
- the invention pertains to the general field of power generating systems and more particularly to a fluid driven apparatus that rotates a power producing generator using an artificially-created unconfined vortex in combination with the prevailing fluid flow.
- the efficiency of a vertical axis windmill is dependent upon the efficiency of its vanes.
- the net efficiency is the difference between the power extracted from the wind when the vane is moving with the wind, less the drag produced when the vane is moving against the wind.
- the prior art vertical drag windmills generally have relatively high starting torques. However, they also have relatively low power outputs per given rotor size and weight.
- the Goldwater patent discloses a windmill that rotates in a horizontal plane about a vertical axis.
- the design includes essentially radial vanes where each vane is effectively a one way valve respective to air flow and each enhance the beneficial actions of the others.
- the vanes in operation effectively simulate a sailing vessel navigating a circular course in wind of constant direction.
- Each of the vanes includes a framework which supports a grid that, in turn, is the supporting means for a plurality of pivotally connected, vertically aligned and overlapping light weight flexible sails. The sails are automatically rotated about the pivotal connection by the force of the wind into positions promoting the revolution of the windmill.
- the storm patent discloses a vertical axis of rotation wind turbine that utilizes sail elements.
- the elements include flexible sails which may be furled and unfurled in response to the speed of the win and which utilize a weight system for varying the area of the sail elements exposed to the wind.
- the Yang patent discloses an improved windmill mechanism for adjusting the position of a wind responsive assembly in relation to the wind.
- the mechanism consists of a fabric sail mounted on the end of an arm which extends from a power output shaft.
- a torque sensor is disposed on the arm to sense the torque contribution through the arm to the power output shaft in response to wind acting upon the fabric sail.
- the position of the fabric sail is adjusted on the arm by means of a control processor which controls a trim motor and a magnetic brake.
- the Corry patent discloses a sail-type windmill that provides high torque without limitations to size.
- Three sails are mounted to a frame for rotation about an axis generally parallel to the planes of the sails.
- the sails are flexible and sheets are provided for mounting the sails.
- Roller reefing is provided for modifying the effective area each sail member presents to the wind, including a spring biased weight associated with each sail and a line extending from the weight for effecting take-up and let-out of the sail and the sheet in response to radial movement of the weight.
- Wind-mills with vertical axis rotors such as the savonius type achieve approximately one third of the above mentioned efficiency and conventional hemispheres and hemi cylinders only about one ninth. Because of these very large machines or devices placed in areas with high winds have been required to economically generate usable electric power.
- the primary object and basic novelty of this invention resides in an entirely new fundamental principle using a turbine that reacts in combination with both the prevailing wind, or water flow and the fluid force produced by an auxiliary fluid mover, which consists of a blower when air is the fluid medium or a water pump when water is the fluid medium, to create an unbalanced force around and above the apparatus that induces an unconfined or free vortex flow.
- This artificially created vortex causes a partial vacuum to occur directly above the apparatus that causes an inward and upward spiral motion of the lower fluid followed by an outward and upward spiral fluid motion.
- FIGURE 1 is a partial isometric view of the preferred embodiment with the vortex fluid mover shown in the proper orientation but detached from the invention.
- FIGURE 2 is a partial isometric view of one of the blades or sails completely removed from the invention for clarity.
- FIGURE 3 is a plan view of the preferred embodiment with the fluid mover axially attached to the power generator frame.
- FIGURE 4 is a schematic block diagram illustrating a possible mode of electrical power generation from the rotation of the rotor.
- FIGURE 5 is a partial isometric view of the preferred embodiment illustrating the fluid flow from the prevailing fluid flow and the unconfined vortex created artificially by the combined shape of the sail and the fluid impinging on the sail from the fluid mover.
- FIGURE 6 is a diagram of the fluid flow as seen from above in plan view.
- the best mode for carrying out the fluid-augmented free-vortex power generating apparatus 10 is presented in terms of a preferred embodiment.
- the preferred embodiment as shown in FIGURES 1 through 6 is comprised of a plurality of aerodynamic shaped sails or blades 20 equally spaced around a hub 22 forming a turbine 24.
- the shape of the sail 20, as illustrated removed from the apparatus 10 in FIGURE 2 not only forms a surface that is driven by the vertical flow of fluid, around the rotor 24 causing rotation but assists in originating the unconfined vortex around the entire apparatus.
- the sail 20 or blade as it is sometimes referred to, is composed of several aerodynamic surfaces including one surface that projects from a hub 26 in the axial center of the turbine 24 and one at an approximate right angle forming a s coop like segment.
- Each sail 20 is rigidly connected to the hub 26 in the center and rotates about the axis as shown in FIGURE 5 and 6. Any number of sails may be used with equal ease however, four individual sails on a single hub have been tested with satisfactory results.
- the sails 20 may be made of any material suitable for the application such as steel, aluminum, fiberglass, composition thermoplastics and the like.
- the hub 26 structurally unites the sails 20 and provides a bearing surface to maintain the position of the turbine 20. Bearings are preferably provided to allow rotation with minimal frictional drag enabling the rotor to spin freely when rotated by the fluid flow.
- the shape of the sail 20 provides a cup like scoop that when reacting with directed fluid, creates the phenomena of a vortex.
- a vortex excitation fluid mover 28 provides this basic rotation ultimately forming the vortex around and above the apparatus.
- the fluid mover 28 which consists of an air mover when air is the fluid medium and a water pump when water is the fluid medium may be of any type device that creates a pressure differential causing the surrounding fluid to flow.
- centrifugal fan or blower impellers will cause the air to flow by the centrifugal force created by rotating the air column enclosed between the blades and the kinetic energy imparted to the air by virtue of the velocity.
- Axial flow fans that produce static pressure from the change in velocity passing through the impeller may also be used.
- any fluid mover may be employed including an airfoil impeller, backward curved or inclined impeller, radial or a forward curved impeller in a scroll housing.
- the fluid mover 28 must develop and supply sufficient velocity pressure on the sails 20 to allow the turbine 24 to develop peripheral velocity that is at least two times the velocity of the prevailing fluid speed in order to create and maintain the desired vortex flow.
- the fluid mover 28 is preferably located on the leeward side at a angle from 181 to 270 degrees from the direction of the prevailing fluid flow, as measured from outside the vortex flow field, and in the direction of rotation.
- FIGURES 5 and 6 depict the phenomena that takes place when the turbine 24 is excited properly by the fluid mover 28.
- the fluid force is depicted in FIGURE 6 approaching the apparatus in a linear relatively constant manner and as the turbine 24 is rotating faster than the prevailing ambient fluid speed, the fluid exhausted from the sails 20 creates a rotational flow in a spiral direction causing a partial vacuum to occur directly above the apparatus, unlike conventional windmills and water wheels that rely on the momentum created by decelerations in the fluid traversing the blades.
- FIGURE 5 depicts this regenerative force in the form of energy from the prevailing fluid "a”, circulating in a regenerative flow "b” leaving the flow field boundary with a diminution of velocity "c".
- the vortex effect is shown around "b” and directly above the turbine generally designed “d” and the vacuum or eye is shown by a dotted line labeled "e”.
- the fluid mover 23 In order to create and maintain the free or unconfined vortex and eliminate the possibility of the vortex moving away from the turbine and traveling outwardly, the fluid mover 23 must be repositioned to maintain the desired alignment of 181 to 270 degrees.
- This alignment may be accomplished in a number of ways, the simplest is depicted in FIGURE 3 and consists of a. ring 30 around the base 32 of the power generator.
- the ring 30 may be fabricated, in any convenient manner as long as the required radial movement is accomplished.
- anyone skilled in the art may accommodate the fluid mover 28 in this repositioning and it may be as simple is the ring 30 or may be electronically sensed and moved by servo-motors. Indeed the principle of positioning the fluid, mover 28 is not altered by the mechanics to obtain the end result.
- auxiliary drive motor 34 to rotate the turbine to initially establish the unconfined vortex in some environmental conditions and to re-establish a new vortex if the critical point of the vortex is lost. While optimum operation does not require this device its use may be necessary in some extenuating circumstances.
- This motor 34 is illustrated generically in a cutaway of FIGURE 1.
- the amount depends on many factors such as fluid density, speed, surface shear and temperature near the ground. Further, the degree of instability in the lower plane all effect the size and energy concentration at the edge of the vortex eye.
- FIGURE 4 indicates one such system developed specifically for this invention using a combination of components all individually well known in the art.
- the motor to drive the vortex excitation fluid mover 28 is designated 34.
- a speed control system 38 consists primarily of belts, gears or the like, connected to the hub 26 of the turbine 24.
- the electrical generator is converted from the mechanical energy by a permanent magnet alternator 40 cascaded to a direct current motor generator 42.
- a solid state DC to AC inverter 44 provides AC power for the output of the device.
- the DC motor generator 42 may be used in lieu of the drive motor 34 where commercial line power is not available using storage batteries 46 to initiate or re-establish the unconfined vortex effect phenomena.

Abstract
Appareil générateur d'énergie (10) à tourbillon libre fonctionnant avec suralimentation en fluide, entraîné par les vents dominants ou par de l'eau, comprenant une turbine (24) qui possède une pluralité d'ailes (20) en forme de godet s'étendant dans le sens axial, montées sur un moyeu (22) tournant librement. Un dispositif de suralimentation en fluide (28) se présentant sous forme d'une soufflante ou d'un ventilateur lorsque le milieu fluide est l'air, ou une pompe à eau lorsque le milieu fluide est l'eau, dirige tangentiellement un écoulement de fluide à très grande vitesse sur les ailettes de la turbine, ceci induisant la rotation et créant un tourbillon libre autour de l'appareil (10). Un générateur d'énergie produit de l'énergie électrique à partir de la rotation du rotor qui tourne en raison de l'action combinée du dispositif de suralimentation en fluide (28) et du mouvement circulaire régénéré accru du fluide créé par le tourbillon libre produit artificiellement.
