Numerical Simulation of Dynamics of the Drop Formation at a Vertical Capillary Tube

The objective of this work is to study the parametric effects on the drop formation. For this, an experimentally verified computational domain that gives an accurate result is developed in the commercial software, FLUENT version 14.0. The numerical simulation of the Navier–Stokes equation has been obtained by combining the volume of fluid model with the finite volume method. To obtain the precise results in the finite volume technique, fine meshing is developed to track the movement of droplet in the air interface. The shape of drop formation obtained through the computational method is being verified with the experimental results available in the literature. The effect of parameters, i.e., viscosity and flow rate, is investigated in detail and also validated with the previous research works. The effect of viscosity on the development of satellite drop formation is also studied. This work is quite good agreement with the experimental work.
