Emulsion-Based Single Drop Generation in a Nonconfined System.

Single drop generation in a nonconfined system during the dripping regime is studied to evaluate the effect of operating conditions on the formation time and drop size. The drop itself is composed of a water-in-oil emulsion that rises from a nozzle into a stationary aqueous phase. This emulsion is non-Newtonian and undergoes shear-thinning behavior, leading to an important decrease in viscosity upon exposure to shear forces.
