AbstractThe dripping-to-jetting transition of a co-flow has been extensively studied. Jetting often occurs due to a sufficiently large inertial force for a non-viscous jet or a considerably large viscous force for a viscous jet. However, in an aqueous two-phase system (ATPS) with an ultra-low interfacial tension, the force required to overcome the tension to form a jet is significantly smaller. We show that the viscous force of a non-viscous jet can be sufficient to induce jetting. The dripping-to-jetting transition is governed by the sum of viscous and inertial force instead of by any of them alone.
