Abstract

Real-time microscopic observations of the membrane emulsification process of some ferrofluids were performed using a polycarbonate membrane module and an optical microscope video system. The droplet growth and the processes of detachment from the membrane cylindrical pores were analyzed via visual images taken during the experimental runs. The work also describes the influence of the continuous phase flow field structure and of flow velocity, as well as the applied magnetic field during membrane emulsification..
