Nozzle assembly for use with a wind lens system for the generation of electric power
A fluid flow nozzle including an elongated first wall and an opposing spaced elongated second wall defining an elongated nozzle volume therebetween, wherein the elongated first wall has a first proximal edge and a first distal edge and wherein the elongated second wall has a second proximal edge and a second distal edge. The nozzle inlet is defined by the first and second proximal edges and an opposing nozzle outlet is defined by first and second distal edges. The elongated nozzle has a cross-sectional shape configured to accelerate a fluid flowing from the nozzle inlet to the nozzle outlet without materially increasing fluid turbulence within the flow.
1. A system to generate electricity using a flow of air, the system comprising:
a turbine assembly, wherein the turbine assembly further comprises:
a cylindrical blade drum; and
a plurality of vertical blades positioned around the cylindrical blade drum;
a plurality of wind lens assemblies, wherein each respective wind lens assembly further comprises:
a respective side wall generally defining a funnel;
a respective vertical slit formed in each respective side wall and defining a respective funnel outlet; and
a respective elongated nozzle coextensive with, and disposed adjacent to, each respective vertical slit, each respective nozzle further comprising:
a respective first wall extending from each respective side wall; and
a respective spaced opposing second wall extending from each respective side wall;
wherein each respective nozzle is configured to enable a substantially laminar flow of air therethrough and direct the flow toward the turbine assembly,
wherein each respective wind lens assembly is disposed external to the turbine assembly whereby each respective funnel outlet of each respective side wall faces the turbine assembly;
an exterior housing assembly surrounding the turbine assembly and each respective wind lens assembly; and
a vertical shaft having a first end and a second end, the first end positioned near the turbine assembly and the second end positioned within a generator, wherein rotation of the cylindrical blade drum causes the generator to operate to generate electricity.
2. The system of claim 1 , wherein each respective nozzle is disposed between each respective vertical slit and the turbine assembly.
3. The system of claim 1 , wherein each respective nozzle directs air flow onto no more than two vertical blades at a time.
4. The system of claim 1 , wherein each respective nozzle is sized to match the dimensions of each respective vertical slit.
5. The system of claim 1 , wherein a respective nozzle further comprises:
at least one body disposed between the respective first wall and the respective second wall for reducing turbulence in air flow through the respective nozzle.
6. The system of claim 5 , wherein the at least one body forms two separate air flows exiting the nozzle.
