| Abstract: | The transient three-dimensional two-phase flow is solved using a volume of fluid method. Simulations of the processes of droplet emergence, growth and detachment arc performed to explicitly track the evolution of the liquid-gas interface. Parametric simulations including the effects of surface tension, density, liquid injection velocity on drop formation are investigated. The axial velocity and pressure on axis while the drop detach are investigated. |
