چکیده
|
In this study, droplet formation in flow-focusing devices was investigated based on two-dimensional numerical simulation with volume of fluid method# two flow regimes were observed in the droplet formation by cfd simulation# in addition, the effect of viscosity of continuous phase and density ratio were investigated# the result showed, when viscosity exceeds about 0#1 kg/m#s the flow regime changes from dripping to jetting# smaller droplets produced with increasing continuous phase viscosity from 0#005 kg/m#s to 1#5 kg/m#s, as well as the size of the droplets produced are different# also when density ratio increases from 0#55 to 1#44, size of droplets and frequency of formation decrease#
