Liquid jet is formed from molten pool surface and the jet keeps growing under influence of driving forces like buoyancy, viscous, surface tension and electromagnetic forces. Whenever the jet achieves crictical stage of stability droplet is formed. I am trying to find the condition for the stability of this jet.
May be you can look into the Rayleigh-Taylor instability criterion for jet breakup.
thank you very much subhashish. I will go through that criteria.
you should look for dimensionless number and flow conditions such as Reynolds and capillary numbers. Velocity, surface tension and viscosity will be the main parameters. Break-up mechanism of droplets depends on those conditions. The study of the wettability is also important for this study
