This paper presents the multiphase 2D axisymmetric simulation of a three-dimensional flow-focusing microfluidic droplet generator using the laminar two phase flow, phase field interface in COMSOL Multiphysics®. The performance of the device is characterized at different flow conditions. The generation frequency and diameter of droplets was studied and shows direct correlation with the flow rates.
