1. A vortex-generating nozzle-end ring comprising: a replaceable vortex-generating nozzle-end ring to enhance mixing of liquids or gases in a pump, the replaceable vortex-generating nozzle-end ring including:a body having an outer periphery and an aperture disposed through the body, the aperture defining an inner periphery of the body, the aperture being a polygonal cross-sectional shape, the body being adaptable to the end of a nozzle to cause low pressure fluid entering the nozzle to exit out of the nozzle to flow as a vortex swirl with increased and high turbulent intensity, the vortex swirl, created by the body, having streamwise vortices on an outer periphery of the jet emanating from the nozzle; andat least two tabs extending from the inner periphery radially inwardly toward the center of the aperture, a first tab of the at least two tabs being diametrically opposed to a second tab of the at least two tabs, each tab of the at least two tabs being non-porous and having a solid surface;wherein each tab of the at least two tabs is selected from the group consisting of tapered prism-shaped, tapered pyramid-shaped, and tapered triangular prism-shaped, the apex of which extend substantially toward the center of the aperture. 2. The vortex-generating nozzle-end ring of claim 1, wherein the body is substantially planar-shaped. 3. The vortex-generating nozzle-end ring of claim 1, wherein the body is substantially planar ring-shaped. 4. The vortex-generating nozzle-end ring of claim 1, wherein each tab of the at least two tabs has a shape that tapers in shape as it extends towards the center of the aperture. 5. The vortex-generating nozzle-end ring of claim 1, further comprising: a flange extending axially from the outer periphery, the flange mountably adaptable for securing to the end of the nozzle. 6. The vortex-generating nozzle-end ring of claim 5, wherein the flange further comprises: at least one of the group consisting of spot welds, rivets, fasteners, threadings, and compression fittings. 7. The vortex-generating nozzle-end ring of claim 1, wherein the body is made from a metal, alloy, or composite material. 8. The vortex-generating nozzle-end ring of claim 1, wherein the at least two tabs occupies less than 30% of the area of the aperture. 9. The vortex-generating nozzle-end ring of claim 1, further comprising: wherein the replaceable vortex-generating ring is configured to allow installation into an ejector, each tab of the at least two tabs being diametrically and symmetrically opposed to the second tab of the at least two tabs, each tab causing a primary fluid to exit the nozzle as a round jet to induce a flow of a secondary fluid to be entrained into a flow channel of the ejector. 10. The vortex-generating nozzle-end ring of claim 1, further comprising: wherein the replaceable vortex-generating ring is configured to allow installation in a thruster opening of a jet engine, each tab of the at least two tabs being diametrically: (a) opposed to the second tab of the at least two tabs, each tab extending inwardly relative to the aperture; or (b) opposed to the second tab of the at least two tabs, each tab extending outwardly relative to the aperture. 11. The vortex-generating nozzle-end ring of claim 1, wherein the at least two tabs occupy less than 15% of the area of the aperture. 12. The vortex-generating nozzle-end ring of claim 1, wherein a base of the at least two tabs is disposed at an angle relative to an inner surface to provide a vortex flow in a counterclockwise direction. 13. An apparatus comprising: a vortex-generating nozzle-end ring including:a substantially planar-ring body having an outer periphery and an inner periphery, the body being mountably adaptable to the end of a nozzle to cause low pressure fluid entering the nozzle to exit out of the nozzle to flow as a vortex swirl with increased and high turbulent intensity, the vortex swirl, created by the body, having streamwise vortices on an outer periphery of the jet of fluid or gas emanating from the nozzle; andat least two solid non-porous tabs extending from the inner periphery radially inwardly toward or outwardly away from the center of the aperture, each tab of the at least two tabs being diametrically opposed to the other tab of the at least two tabs;wherein each tab of the at least two tabs is selected from the group consisting of tapered prism-shaped, tapered pyramid-shaped, and tapered triangular prism-shaped, the apex of which extend substantially toward the center of the aperture. 14. The apparatus of claim 13, wherein each tab of the at least two tabs has a shape that tapers in form as it extends with respect to the center of the aperture. 15. The apparatus of claim 13, further comprising: a flange circumscribing and extending axially from the outer periphery, the flange mountably adaptable for securing to the end of the nozzle. 16. The apparatus of claim 15, wherein the flange further comprises: at least one of the group consisting of spot welds, rivets, fasteners, threadings, and compression fittings. 17. A vortex nozzle to enhance mixing, the vortex nozzle comprising: a housing having a central longitudinal axis, the housing having an inlet and an outlet; anda vortex-generating nozzle-end ring disposed on the outlet to enhance mixing of liquids or gases in a pump, the vortex-generating nozzle-end ring comprising:a body having an outer periphery and an aperture disposed through the body, the aperture defining an inner periphery of the body, the aperture being a polygonal cross-sectional shape, the body being detachably adaptable to the end of the nozzle to cause low pressure fluid entering the nozzle to exit out of the nozzle to flow as a vortex swirl with increased and high turbulent intensity, the vortex swirl, created by the body, having streamwise vortices on an outer periphery of the jet emanating from the nozzle; andat least two tabs extending from the inner periphery radially inwardly toward the center of the aperture, each of the at least two tabs being non-porous, a first tab of the at least two tabs being diametrically opposed to a second tab of the at least two tabs;wherein each tab of the at least two tabs is selected from the group consisting of tapered prism-shaped, tapered pyramid-shaped, and tapered triangular prism-shaped, the apex of which extend substantially toward the center of the aperture. 18.
