Method and apparatus for total energy systems
This patent describes an apparatus for jet pumping comprising a primary nozzle coupled to a high temperature-high pressure combustion chamber, constructed for over two atmospheres and to withstand temperatures over 1500/sup 0/F. at least one secondary supply port substantially tantential to a quasi doughnut shaped secondary supply housing. The axis of the housing is concentric with and attached to the nozzle, such that the inside diameter of the discharge annulus from the housing conforms in diameter with and attaches to the nozzle at some distance aft of the nozzle discharge extremity, and the outside diameter of the discharge annulus conforms with and attaches to the aft extremity of a cylindrical-to-diverging mixing tube for the jet pumping. The apparatus for jet pumping is constructed to withstand combustion temperatures up to stoichiometric levels with the mixing tube discharge area designed for fluids flowing at subsonic velocities, and comprising further a secondary flow path of diminishing cross-section in the supply housing, equally spaced radial vanes provided between the outer wall of the nozzle and the inner wall of the mixing tube, the down stream extremities thereof terminating at some point down stream of the discharge annulus. The warp of the vanes is shaped for directing centripetal flow in one direction and inclined toward increasing axial flow in the other direction, a teardrop-shaped body located on the center line of and partailly inside of the nozzle extremity so as to form a primary annular discharge orifice. The axial cross-section of the orifice conforms the requirements of up-to-supersonic primary discharge flows, the teardrop being held in place at the down stream extremity by suitable means.
