Abstract:
A pipe of unique design capable of augmenting any flow, including but not limited to: gas, liquid, particulate, plasma, and/or other fluid state or any combination thereof whether the flow is human and/or naturally made such that the tunnel produces a net decrease in pressure and a net increase in speed of a flow. The tunnel(s) can be used to augment flow to, from, in, at, and/or around turbines and/or rotors.

       [0001]    This Invention, The F.U.N. Tunnel(s) claims the benefit of the filing date of provisional patent 61/459,866 with a US filing date of Dec. 20, 2010 and a foreign filing date of Jan. 21, 2011. 
     
    
     DESCRIPTION 
       [0002]    1. Technical Field 
         [0003]    The present invention relates to venturi tunnel(s) used for a wide variety of industrial uses including but not limited to directing flows to, at, in, and/or around electricity producing turbines. 
         [0004]    2. Background 
         [0005]    The F.U.N. Tunnel(s) is a unique type of pipe(s). It utilizes a series of venturis to increase the speed and decrease the pressure of matter flowing over a distance. Both U.S. Pat. No. 4,690,245 and U.S. Pat. No. 4,936,413 claim the use of a series of venturis in automotive applications, however The F.U.N Tunnel(s) is materially different because the peak cross sectional areas of its chambers decrease from entrance chamber to middle chamber/chambers to exit chamber, whereas both U.S. Pat. No. 4,690,245 and U.S. Pat. No. 4,936,413 claim the benefit of a series of venturis with equal peak cross sectional across all chambers along the entire length of their claimed inventions. This difference is material because the peak cross sectional areas of the chambers must decrease to generate a net increase in speed and a net decrease in pressure in matter flowing over a distance. If the chambers are of the same peak cross sectional area, the flow will return to baseline pressure and speed, the same pressure and speed at the entrance of the tunnel(s). 
         [0006]    Furthermore, U.S. Pat. No. 4,213,939 is a carbon black reactor that utilizes a series of venturis with varying peak cross sectional areas, however this invention is materially different from The F.U.N. Tunnel(s) because the peak cross sectional areas of the chambers increase from entrance chamber to middle chamber to exit chamber whereas the peak cross sectional areas of the chambers in The F.U.N Tunnel(s) decrease from entrance chamber to middle chamber(s) to exit chamber. The configuration of the venturis in U.S. Pat. No. 4,213,939 cause a net decrease in speed and a net increase in pressure, whereas the venturis in The F.U.N Tunnel(s) cause a net increase in speed and a net decrease in pressure of matter flowing over a distance. The F.U.N. Tunnel functions in the same way as a conventional venturi, however it can perform this function over a distance. 
       BRIEF SUMMARY OF THE INVENTION 
       [0007]    The F.U.N. Tunnel(s) is a pipe(s) designed to increase the speed and decrease the pressure of matter flowing over a distance.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0017]    The F.U.N. Tunnel(s) is a system of pipe(s) used to augment flows. It is an open pipe(s) comprised of a converging entrance chamber, diverging then converging middle chamber(s), and a diverging exit chamber resulting in a pipe with multiple constriction points creating a series of venturis with peak cross sectional areas of the chambers decreasing from entrance chamber to middle chamber(s) to exit chamber, thus generating a net decrease in pressure and a net increase in speed of the matter flowing through the length of the invention, simply put the tunnel(s) generates an decrease of pressure and an increase of speed in matter flowing over a distance. This is accomplished because the pressure at the entrance of a venturi is lower than the pressure at the entrance of a previous venturi along the length of the invention. The F.U.N. Tunnel can be used throughout industry wherever a flow is present. Some of the industrial uses include nozzles, particle accelerators, turbine ducts, and stents.
