The Primary Breakup of a Round Liquid Jet by a Coaxial Flow of Gas
Numerical simulations are conducted to investigate the primary atomization of a round liquid jet surrounded by a coaxial flow of gas. A Refined Level Set Grid (RLSG) method coupled to a Lagrangian spray model is used to capture the whole breakup process of the liquid jet. In the near field of the liquid jet, where the primary breakup occurs, motion and topological changes of the liquid jet are ...
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 کاملDroplet collisions after liquid jet breakup in microgravity conditions
The droplet dynamics and collisions after a liquid jet breakup have been experimentally studied in low gravity conditions. An experimental setup was designed in order to be used at the I.N.T.A. Drop Tower, which allows for 2.1 seconds of microgravity. The dynamics of distilled water jets injected into a rectangular tank was recorded by means of a high-speed video camera. Observations of the dro...
متن کاملLiquid jet instability and dynamic surface tension effect on breakup
We studied the instability of a liquid jet by confocal microscopy, a non-invasive three-dimensional imaging technique. The amplitude of jet oscillation can be measured from its early stage to the vicinity of the jet breakup with a radial resolution of 80 nm. A continuous jet with a diameter of 100 μm and mean velocity of 5.6 ms was perturbed at a frequency of 11.8 kHz. The growth rate of the si...
متن کاملA geometrical constraint for capillary jet breakup
The formation of thinning filaments is commonly observed previously to the break-up of a very viscous jet. This paper shows that a fluid under capillary forces cannot break-up through the uniform collapse of a filament. r 2003 Elsevier Inc. All rights reserved. MSC: 35Q30; 35R35; 74H35
