Abstract:In this paper, we study numerically the motion of a pair of double-emulsion (DE) droplets in a two-dimensionally singly constricted capillary tube. The momentum and continuity equations are solved using the finite element method, and the interface is tracked via the level set method. The influence of interfacial tension, viscosity and density ratios, droplet size, pore throat size, and geometrical shape on the droplets' local extra pressure drop and instantaneous velocities are calculated. It is found that at … Show more
