摘要：

Oil-water emulsions consist of droplets that are approximately spherical in shape and with a distribution in size. An image processing technique that can be used for studying emulsion droplet stability behaviour in multiphase flow has been developed. In this work, the developed technique is used to study a model system, comprising Nexbase (with and without SPAN 80 surfactants) oil and saline water emulsion in a stirred tank system. A state of the art stirred tank experimental set up was constructed that measured dynamic droplet size evolution with varying impeller speed and torque. The equilibrium droplet size measurement and torque data were used to validate with theoretical inertial (Hinze model) and viscous subrange models. Besides, this method was successfully used to obtain droplet size relaxation coefficients with varying impeller speeds. (C) 2017 Published by Elsevier B.V.
