Abstract
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.
Claims20
A method comprising:
- attaching a nozzle with a streamlined nozzle opening to a diffuser such that the nozzle spans at least the entire length of the diffuser to direct an air flow through the streamlined nozzle opening into a shrouded wind turbine;
- increasing a wind speed approaching a set of turbine blades within the shrouded wind turbine configuration that allows to start-up a wind turbine at a lower free air speed and to increase an output power of the shrouded wind turbine;
- and
- inducing a recirculation of the air contained within the shroud configuration such that there is, around the diffuser inlet, an inward flow direction from the nozzle to the diffuser that interacts and directs the air flow into the wind turbine to increase the output power generated by the shrouded wind turbine.
A system comprising:
- a diffuser:
- to collect and accelerate an air flow to a set of turbine blades within a shrouded wind turbine configuration,
- to increase a wind speed approaching the set of turbine blades,
- to increase an output power generated;
- and
- a nozzle with a streamlined nozzle opening:
- to direct the air flow through the streamlined nozzle opening into the set of turbine blades,
- to induce a recirculation within the shrouded wind turbine configuration to interact with the air flow and direct it into the set of turbine blades,
- to increase the wind speed approaching the set of turbine blades,
- to increase the output power.
A method comprising:
- increasing a pressure differential between an entrance and an exit of a shrouded wind turbine configuration to draw air flow into a diffuser of the shrouded wind turbine configuration;
- directing the air flow into the diffuser through a streamlined nozzle opening of a nozzle attached to the diffuser;
- and
- recirculating the air within the shrouded wind turbine configuration to interact and direct the air flow approaching a wind turbine into the diffuser.
