Droplets formation in turbulent mixing of two immiscible fluids in a new type of static mixer

The emulsification process in a static mixer high-efficiency vortex in turbulent flow is investigated. This new type of mixer generates coherent large-scale structures, enhancing momentum transfer in the bulk flow and hence providing favourable conditions for phase dispersion. The generation of the emulsion is described via a classical size-distribution function characterised by the Sauter diameter and a dispersion factor. (C) 2003 Elsevier Science Ltd. All rights reserved.
