Abstract: This research validates the computational results regarding the effects of viscosity, the flow rate on the dynamics of drop formation in the continuous jetting mode with the experimental results available in the literature. In this research, volume of fluid method is used for tracking the droplet during detachment process. Various stages of drop formation including ejection and neck development of liquid thread and its breakoff into primary drops are studied. The deviation of pressure is also analyzed. The variation of the smallest width of thread and thread length is also studied for various time periods. It is also observed that the size of the primary drop increases slightly with the increase in surface tension and decreasing viscosity whereas while the effect of density on the size of the primary drop is negligible. Furthermore, mathematical models using power law, allometric curve and exponential decay function were also constructed. The coefficient of determination also achieved the higher values (0.97-0.99). Drop formation process is widely used in IC engines for atomization purposes in the paint industry and especially in the medical field for determining certain diseases.
