Induced-Flow Wind Power System

A high efficiency Induced-Flow Wind Power System configured for engaging and converting both the potential (to pull) and kinetic (to-push) wind energies to effective mechanical power;

• the induced-flow wind power system comprising:
• a. a passive-flow nozzle, wherein said passive-flow nozzle is a venturi flow field having an intake, throat (constriction), exhaust (diffuser), wherein said passive-flow nozzle has a vacuum inlet interposed between said throat and said diffuser section of said passive-flow nozzle, wherein said passive-flow nozzle is configured horizontally (parallel to the ground) at an elevation above the ground;
• wherein said passive-flow nozzle is configured to harness and accelerate higher altitude higher velocity open flow wind through said venture flow field of said passive-flow nozzle, wherein accelerating the open flow wind (airflow) through said venturi flow field produces low pressure in the said throat and said vacuum inlet section, wherein the accelerated wind diffuses and evacuates through said exhaust section of said passive-flow nozzle, wherein the induced low pressure produces a vacuum effect in said vacuum inlet section;
• b. aerodynamic airfoil configuration, connected externally to said passive-flow nozzle;
• wherein, said aerodynamic airfoil configuration has a curved form;
• wherein the curved form of said aerodynamic airfoil configuration accelerates the ambient wind over the exterior of said passive-flow nozzle to produce low pressure at said exhaust section of said passive-flow nozzle;
• wherein the produced low pressure generates an additional evacuation and acceleration force for the harnessed open flow wind in said passive-flow nozzle.
• c. an active-flow nozzle, wherein said active-flow nozzle is a venturi flow field having an intake, throat (constriction), and diffuser cone, wherein said active-flow nozzle is configured below said passive-flow nozzle, wherein said diffuser cone of said active-flow nozzle is vertically coupled with said passive-flow nozzle through said vacuum inlet, wherein said throat of said active-flow nozzle is configured at lower elevation relative to said passive-flow nozzle, wherein said intake of said active-flow nozzle is oriented parallel in the direction of the open flow wind;
• wherein, said active-flow nozzle is configured to harness and direct open flow wind through the flow field of said active-flow nozzle;
• wherein the vacuum effect in said passive-flow nozzle coupled with said diffuser cone of said active-flow nozzle pulls and evacuates the harnessed wind through said active-flow nozzle, wherein said-active flow nozzle venturi flow field is induced by the evacuation force produced by said passive-flow nozzle, causing acceleration of harnessed wind in said active-flow nozzle through said turbine.
• d. a housing, interposed within said throat section of said active-flow nozzle between said intake and said diffuser cone, wherein said housing comprises a transitionally fluid portion of said venture flow field of said active-flow nozzle;
• wherein, said housing is configured to distributes a 360-degree uniform induced airflow (torque) to said turbine;
• e. a turbine, encased in said housing within the flow field of said active-flow nozzle, wherein said turbine has a radial-to-axial flow turbine configuration, such as a Francis-type turbine, wherein said turbine has a vertically or horizontally oriented turbine axel, runner blades, spiral casing, stay vanes and draft tube, wherein said turbine is configured for operation with induced airflow;
• wherein, said turbine is configured to (i) effectively divert the radial intake airflow (from the active-flow nozzle intake) to axial flow, (ii) discharge the airflow to the active-flow nozzle diffuser cone, (iii) convert potential and kinetic wind (airflow) energy to rotational mechanical power, and (iv) as a flywheel, stabilize energy production during wind gusts.
