  • Patent number: 5738281
    Abstract: Use of a shrouding gas to combine with and protect a turbulent gas jet issuing from an orifice enables control of a gas jet stream composition downstream from the orifice. The natural aspiration rate of the gas jet is used to determine the flowrate of shrouding gas which is introduced around the gas jet in a soft gas cushion which does not disrupt the flow pattern of the gas jet but instead is entrained into the jet stream to the exclusion of ambient gases in the atmosphere. Preferably shrouding gas is replaced at least at the rate at which it is entrained. Apparatus for this process uses a porous shroud, preferably of metal foam, through which shrouding gas flows evenly around the gas jet as it issues from a nozzle orifice. Provision for tangential entry of shrouding gas into a manifold which feeds the porous shroud prevents the shrouding gas from impinging upon the porous shroud and causing uneven flow around the gas jet.

  • Patent number: 5735469
    Abstract: A compact diffuser for recovering pressure from a supersonic flow with boundary layers. Sharp splicer plates near the wails form boundary layer scoops and separate the flow into an inner coreflow chapel and outer chambers containing small supersonic ejector nobles. The coreflow without boundary layers undergoes a single near-normal shock to recover pressure. The boundary layers are pumped to the recovery pressure in the outer ejector chambers. The subsonic part of the boundary layer flow to the outer chambers can be choked against boundary layer scoop inlet corners to isolate the upstream flow. The leading edge angle of the splicers may be selected to help induce coreflow shocking.

  • Patent number: 5565241
    Abstract: A convergent end-effector which combines a liquid and dry flow external to a spray nozzle eliminates clogging problems common in the prior art spray coating systems. The end-effector utilizes a nozzle with an orifice and at least one atomizing hole, a conduit for directing a liquid resin through the nozzle and an outer housing disposed around said conduit to form a cavity. Reinforcing material enters the cavity on an gas stream supplied and controlled by an eductor located prior to the outer housing, in the direction of the nozzle, and at an angle of less than about 90.degree. with respect to the conduit. The end of the conduit near the nozzle is preferably angled toward the nozzle to further direct the reinforcing material into the liquid resin.

    Abstract: A fluid injection device and method includes an upstream conduit, downstream conduit, a support for holding the upstream and downstream conduit with their upstream and downstream passageways aligned and maintaining a gap between the adjacent ends of the conduits, and a secondary fluid source connectable to the gap for injecting secondary fluid into the gap and downstream throat. The upstream passageway includes an acceleration nozzle for accelerating the velocity of the fluid flow so that the pressure exerted by the fluid on the walls of the upstream passageway is substantially reduced and the reduced pressure is maintained across the gap. The downstream conduit includes a downstream passageway which maintains the accelerated velocity of the primary fluid and which conducts the accelerated fluid to a deceleration nozzle. The secondary fluid source injects secondary fluid into the gap and downstream conduit at a preselected higher pressure than the fluid exiting the upstream throat.

  • Patent number: 5256375
    Abstract: A mixing device for use in a duct (12), particularly for use when testing the efficiency of a filter (10) in the duct by aerosol injection, consists of a pipe (24) with a closed end arranged near the middle of the duct (12). The other end of the pipe is connected to a source (26) of compressed air. Near the closed end are one or more narrow holes (28) so that narrow air jets are created across the width of the duct. The air jets create large-scale turbulence in air flowing in the duct, even where that air flow was already turbulent, such that thorough mixing is achieved within as little as two duct diameters or less, while producing negligible pressure drop. The mixing device may be combined with an aerosol injector (20, 22).
