Abstract: Oil-in-water(o/w) emulsions were produced with a membrane emulsification system. The effect
of the continuous phase viscosity on the emulsification was studied. The theoretical
analyses show that the continuous phase viscoeity influences not only the flow field of the
continuous phase but also the interfacial tension. The droplet size distribution and
disperse phase flux for different continuous phase viscosity were investigated
experimentally at constant wall shear stress and constant volume flow rate of the
continuous phase respectively.

Key words: membrane emulsification, viscosity, continuous phase
