Jet pump system and method with improved efficiency

Abstract

The present disclosure is of a jet pump system, and reverse power generation system and other desirable applications consisting of an impeller with inlet vortex vanes and outlet vortex vanes. The inlet vortex vane induces rotational movement on mass entering the impeller inlet. The outlet vortex vanes remove swirl from mass exiting the impeller outlet. Embodiments include a jet pump system involving a pulley and belt which can allow for obstruction free movement of mass. In another embodiment the impeller is connected via an electromagnetic connection. In another embodiment the impeller acts as a rim-driven generator of electrical power. In another embodiment the drive pulley is a centrifugal clutch or uses a chain sprocket or tandem jet system in series.

 wherein a mass flow passing through each of a plurality of areas formed between adjacent blades of the plurality of blades is isolated from another mass flow passing through others of the plurality of areas formed between other adjacent blades of the plurality of blades; and 
 wherein each of the plurality of blades is angled so that the leading edge of one of each of the plurality of blades overlaps the trailing edge of an adjacent one of the plurality of blades thereby preventing the mass flow from passing through each of the plurality of areas without impinging upon one of the plurality of blades; 
   an inlet vortex vanes disposed in a coaxial arrangement in front of the impeller from a point of view of the mass flow, the inlet vortex vanes including a plurality of inlet vanes, a trailing edge of each of the plurality of inlet vanes shaped to match a shape of the leading edge of each of the plurality of blades, the inlet vortex vanes disposed to minimize a gap between the trailing edge of each of the plurality of inlet vanes and the leading edge of each of the plurality of blades; and   an outlet vortex vanes disposed in a coaxial arrangement to the rear of the impeller from the point of view of the mass flow, the outlet vortex vanes including a plurality of outlet vanes, a leading edge of each of the plurality of outlet vanes shaped to match a shape of the trailing edge of each of the plurality of blades, the outlet vortex vanes disposed to minimize a gap between the leading edge of each of the plurality of outlet vanes and the trailing edge of each of the plurality of blades.   
     
     
         2 . The impeller assembly of  claim 1  wherein a ratio of a length of the outer edge of each of the plurality of blades to an inner diameter of the outer housing is substantially 0.8. 
     
     
         3 . The impeller assembly of  claim 1  wherein the plurality of axial blades includes four blades, the plurality of inlet vanes includes 4 inlet vanes, and the plurality of outlet vanes includes 4 outlet vanes. 
     
     
         4 . The impeller assembly of  claim 1  wherein the plurality of inlet vanes are angled to have an angle substantially the same as the angle of the plurality of blades of the impeller in proximity to the leading edge of the plurality of blades. 
     
     
         5 . The impeller assembly of  claim 1  wherein the plurality of inlet vanes are angled to minimize the disturbance experienced by the mass flow as it exits the inlet vortex vanes and enters the impeller. 
     
     
         6 . The impeller assembly of  claim 1  wherein the plurality of outlet vanes are angled to have an angle substantially the same as the angle of the plurality of blades of the impeller in proximity to the trailing edge of the plurality of blades. 
     
     
         7 . The impeller assembly of  claim 1  wherein the plurality of outlet vanes are angled to have an angle to reduce mass disturbance of the mass flow as it exits the impeller and enters the outlet vortex vanes. 
     
     
         8 . The impeller assembly of  claim 1  wherein the plurality of outlet vanes are angled to have an angle to direct the trajectory of mass exiting the impeller to minimize swirl.
