Breakup of electrified jets
Breakup of electrified jets is important in applications as diverse as electrospraying, electroseparations and electrospray mass spectrometry. Breakup of a perfectly conducting, incompressible Newtonian liquid jet surrounded by a passive insulating gas that is stressed by a radial electric field is studied by a temporal analysis. An initially quiescent jet is subjected to axially periodic shape...
متن کاملBreakup of Liquid Jets
For fundamental analysis of the transport of mass or heat in a dispersed system, accurate knowledge of behavior of jet is prerequisite. For generation of high interfacial area breaking of liquid jet in to small droplet is necessary. Liquid jet breakup is a complex phenomenon and dependent on many factors like velocity of jet, pressure difference, geometry of nozzle, temperature of both fluid, p...
متن کاملDelayed capillary breakup of falling viscous jets.
Thin jets of viscous fluid like honey falling from capillary nozzles can attain lengths exceeding 10 m before breaking up into droplets via the Rayleigh-Plateau (surface tension) instability. Using a combination of laboratory experiments and WKB analysis of the growth of shape perturbations on a jet being stretched by gravity, we determine how the jet's intact length l(b) depends on the flow ra...
متن کاملPrimary Breakup of Turbulent Round Liquid Jets in Uniform Crossflows
Anexperimental investigation of the deformation andbreakupproperties of turbulent round liquid jets in uniform gaseous crossflows is described. Pulsed shadowgraphandholographobservationswere obtained for turbulent round liquid jets injected normal to air crossflow in a shock tube. Crossflow velocities of the air behind the shock wave relative to the liquid jet were subsonic (36–90 m=s) and the ...
متن کاملBreakup of round Nonturbulent Liquid Jets in Gaseous Crossflows
An experimental investigation of the primary breakup of nonturbulent round liquid jets in gas crossflow is described. Pulsed shadowgraph and holograph observations of jet primary breakup regimes, conditions for the onset of breakup, properties of waves observed along the liquid surface, drop sue and velocity properties resulting from breakup and conditions required for the breakup of the liquid...
