Abstract

Highlights: Experimental characterisation of the dripping regimes and jetting transitions from a dripping faucet at high Bond numbers. Discovery of new regimes with satellite formation not present at small Bond numbers. Quantification of the hysteresis of the dripping-jetting transition for liquids different from water. Abstract: We report experiments on the dripping dynamics and jetting transitions that take place when a liquid is injected vertically downwards at a constant flow rate, for wide ranges of the liquid viscosity and injector radius. We explore values of the Bond number significantly larger than in previous works, revealing the existence of period-2 dripping regimes with satellite formation that do not exist at small Bond numbers. In addition, we quantify the influence of liquid viscosity on the hysteresis associated with the dripping-jetting transition, that had previously been studied only for the particular case of water.
