Abstract
Numerical investigation of capillary driven droplet breakup due to fluiddynamic instabilities
Highlights
Emulsions as liquid/liquid formulations are widely used in the industry
The premix membrane emulsification is a low shear stress process which is relevant for handling shear sensitive media, for instance in biological systems
The influence on the droplet breakup is explained by lowering the minimum emulsification pressure for membrane applications
Summary
Emulsions as liquid/liquid formulations are widely used in the industry. They play an important role in pharmaceutical- food- and cosmetic applications. The premix membrane emulsification is a low shear stress process which is relevant for handling shear sensitive media, for instance in biological systems. It was first introduced by Suzuki et al [1] and obtains the advantage of adjusting the final droplet size with an narrow size distribution. They concluded, that most surface interactions increase the contact angle towards 90°, either through surfactant or the oil that is used It seems that the emulsification process is deeply understood, the droplet breakup mechanism is still quite unknown, especially under the consideration of membrane wettability
