FIG. 3. Computed evolution of the minimum radius of the water neck during the
drop formation and detachment process. The instantaneous neck radius of water
and the inertio-capillary fit are shown. The inset shows a self-similar nature of neck
thinning dynamics close to a pinch-off moment. The characteristic cone angle of
18.1◦
as predicted by Day et al.50 and visualized in experiments52 is captured
well using the VOF method.
