Abstract

The present invention includes a nozzle device and method for forming a composite fluid. The nozzle device generally comprises a nozzle portion connected to a main body. The main body includes an inner axial bore extending therethrough. An annular wall extends radially therefore and an annulus extends from an outer perimeter of the annular wall. The annulus and the annular wall define an annular chamber at least partially open to the atmosphere. A portal fluidly communicates the bore with the annular chamber. The nozzle portion includes a converging nose section also having an internal axial bore extending therethrough. An annular collar extends from the nose section and disposes at least partially within the annular chamber. A first tube for transporting a first fluid disposes within the axial bore of the main body and nose section, terminating at an exit port of the nozzle section. A second tube for transporting a second fluid disposes within the axial bore of the main body, terminating proximate the portal. A propellant fluid introduced under pressure into the bore of the main body directs the second fluid exiting the second tube into the annular chamber through the portal. Upon entering the annular chamber, the propellant fluid and the second fluid pass about the annular collar and travel along an outer surface of the nose section toward the exit port. The propellant fluid and the second fluid admix with the first fluid exiting the first tube and exit port to form the composite fluid outside the nozzle.
