Deformation and breakup of droplets suspended in another liquid
Abstract
A theoretical analysis was carried out on the deformation of a droplet suspended in a steady extensional flow field, where both fluids may be represented by the second-order fluid model. The study took into account the effects of the viscosity, the elasticity and the interfacial tension of fluids concerned. The shape of a deformed droplet is determined theoretically by solving the equations of motion for both fluids, the droplet phase and suspending medium. A perturbation technique was employed to handle nonlinear terms appearing in the equations of motion, and an iteration method was used in determining the shape of the droplet undergoing extensional deformation. Series solutions of stream functions inside and outside the droplet, the pressure field around the droplet and the deformation of droplet were obtained.
