Transformation of the bridge during separation of a droplet

The geometry of flows resulting from separation of hanging drops of liquids with significantly different physical properties (alcohol, water, glycerin, oil) was studied by high-speed video recording. The dynamics of the processes is studied for characteristic shapes of bridges: with slightly nonuniform thickness and with thinning of the upper and lower ends. It is shown that the change of the shape of the separated bridge has a number of stages determined by the properties of the liquid. As a result, the bridge is transformed into a small droplet - a satellite droplet.
