Item-typ:Veröffentlichung, Einfluss der Mikrofluidik beim Membranemulgieren: Differentielle Betrachtung mittels numerischer Simulation und Experiment(2012-03-19); ; ; The Influence of the local flow conditions on the membrane emulsification is examined by computational fluid dynamic. Pressure, flow velocity and pore diameter determine the droplet forming. Weber number We and Capillary number Ca found as dimensionless quantities to describe the membrane emulsification process. The mechanism of droplet breakup inside and outside the membrane is examined. Droplet breakup and coalescence processes result in topological change of the phase interface. A numerical model is developed, that allows describing droplet interactions including contact, coalescence and rebound, depending on the local flow conditions. The model is used for numerical simulation of multi disperse, multiphase fluid flow processes.Dissertation295 186
