Disclosed are a system, a method and an apparatus of diffuser nozzle augmented wind turbine. In one embodiment, a method includes attaching a nozzle with a streamlined opening to a diffuser to direct an air flow into a wind turbine. In addition, the method includes increasing a wind speed approaching a set of turbine blades within a shrouded wind turbine configuration. The method also includes recirculating the air within the shroud configuration to increase an output power generated through the wind turbine. The system is composed of diffuser and nozzle integrated and non-integrated with and without a flange. In one embodiment, a method includes increasing a pressure differential of a wind turbine.

1. A method comprising: attaching an end of a nozzle with a streamlined opening to an end of a diffuser such that the nozzle spans at least an entire axial length of the diffuser and subsumes the diffuser therewithin starting from the end of the attachment of the nozzle to the end of the diffuser to direct an air flow through the streamlined opening into a shrouded wind turbine;attaching the nozzle to a flange of the diffuser to separate a front inlet air space and a back exit air space such that a front cavity is formed in the front inlet air space by an inner side of the nozzle, a front side of the flange and an outer side of the diffuser, wherein air collected in the front inlet air space by the nozzle is configured to flow through the shrouded wind turbine in a main thrust of the air flow before exiting through the diffuser to the back exit air space;inducing directed recirculation of recirculated inlet air in the front inlet air space using the front cavity formed by the inner side of the nozzle, the front side of the flange and the outer side of the diffuser;controlling a flow pattern of the recirculated inlet air in the front cavity within the front inlet air space using a controlled surface of the front cavity formed by a coordinated shaped inner side of the nozzle, a coordinated shaped front side of the flange and a coordinated shaped outer side of the diffuser;creating a stagnation point at a tip of the nozzle configured to receive the air flow at an end of the nozzle opposite to the end of the attachment thereof to the end of the diffuser based on sharply curving a surface of the nozzle solely in an immediate vicinity of the tip in comparison to other portions of the surface of the nozzle, the stagnation point rendering the tip of the nozzle susceptible to a peak pressure region with respect to the air flow, an area around the stagnation point being a high pressure region with respect to the air flow, and an area at the end of the diffuser being a low pressure region with respect to the air flow;increasing an output power generated by the shrouded wind turbine by increasing wind speed of the air flow through reduction of wind friction along a path of the air flow before reaching the shrouded wind turbine;increasing the wind speed of the air flow by reducing a wind friction between the main thrust of the air flow and the recirculated inlet air in the front cavity along the path of the air flow before reaching the shrouded wind turbine; andreducing the wind friction between the main thrust of the air flow and the recirculated inlet air in the front cavity by controlling at least one of a physical shape, a curvature, and a physical dimension of the controlled surface of the front cavity to direct the flow pattern of the recirculated inlet air in the front cavity such that the recirculated inlet air in the front cavity flows in a parallel manner with the main thrust of the air flow at an interface where the recirculated inlet air in the cavity meets the main thrust of the air flow. 2. A system, comprising: a shrouded wind turbine with a set of turbine blades to generate electricity based on wind energy as air flows through the shrouded wind turbine;a diffuser of the shrouded wind turbine to slow down the air flow before the air flow mixes smoothly with atmosphere;a nozzle with a streamlined opening, an end of which is attached to an end of the diffuser such that the nozzle spans at least an entire axial length of the diffuser and subsumes the diffuser therewithin starting from the end of the attachment of the nozzle to the end of the diffuser to direct the air flow through the streamlined opening into a shrouded wind turbine; anda flange of the diffuser attached to both the diffuser and the nozzle to separate a front inlet air space and a back exit air space such that a front cavity is formed in the front inlet air space by an inner side of the nozzle, a front side of the flange and an outer side of the diffuser, wherein air collected in the front inlet air space by the nozzle is configured to flow through the shrouded wind turbine in a main thrust of the air flow before exiting through the diffuser to the back exit air space,wherein directed recirculation of recirculated inlet air in the front inlet air space is induced using the front cavity formed by the inner side of the nozzle, the front side of the flange and the outer side of the diffuser,wherein a flow pattern of the recirculated inlet air in the front cavity within the front inlet air space is controlled using a controlled surface of the front cavity formed by a coordinated shaped inner side of the nozzle, a coordinated shaped front side of the flange and a coordinated shaped outer side of the diffuser,wherein a stagnation point is created at a tip of the nozzle configured to receive the air flow at an end of the nozzle opposite to the end of the attachment thereof to the end of the diffuser based on sharply curving a surface of the nozzle solely in an immediate vicinity of the tip in comparison to other portions of the surface of the nozzle, the stagnation point rendering the tip of the nozzle susceptible to a peak pressure region with respect to the air flow, an area around the stagnation point being a high pressure region with respect to the air flow, and an area at the end of the diffuser being a low pressure region with respect to the air flow,wherein an output power generated by the shrouded wind turbine is increased by increasing wind speed of the air flow through reduction of wind friction along a path of the air flow before reaching the shrouded wind turbine,wherein the wind speed of the air flow is increased by reducing a wind friction between the main thrust of the air flow and the recirculated inlet air in the front cavity along the path of the air flow before reaching the shrouded wind turbine, andwherein the wind friction between the main thrust of the air flow and the recirculated inlet air in the front cavity is reduced by controlling at least one of a physical shape, a curvature, and a physical dimension of the controlled surface of the front cavity to direct the flow pattern of the recirculated inlet air in the front cavity such that the recirculated inlet air in the front cavity flows in a parallel manner with the main thrust of the air flow at an interface where the recirculated inlet air in the cavity meets the main thrust of the air flow.
