Simulation of Gravity-Driven droplet Formation and Detachment with Lattice Boltzmann Method

There are many common examples of multiphase flows in a wide range of natural phenomena and engineering applications; i.e. printing, spray systems, combustion, and more. Regarding to both fundamental and developing reasons, understanding the multiphase flows is essential. As one of the most important multiphase flows, droplet involving phenomena has a significant importance from engineering and scientific points of view [۱,۲]. In this field, formation and detachment of a single droplet under effects of gravityforce in the absence of co-flowing gas stream is of interest. The mechanism of drops forming from a nozzle has been observed in many industrial applications; i.e. printing, spray cooling, emulsion formation, and more [۳].
