Stirred tank membrane emulsification using flat metallic membranes: A dimensional analysis

► Monodisperse O/W emulsions were prepared with flat metallic membranes. ► The performance of the system can be described by dimensional analysis. ► The capillary number is the most important group according to prediction models. ► Impeller rotational speed and continuous phase viscosity affect droplet size much. ► Droplet size can be estimated with correlations based on Euler number.
