The Influence of Geometry on the Stability of Emergent Droplets

A study of the stability of microdroplets is undertaken numerically to asses the effect of geometry. A droplet emerges from a hole or a pore and it completely detaches when a certain volume of liquid is accumulated. Present study assesses this volume for a polygonal pore, and for a circular hole in a curved surface. Notable differences exist between the stability limits of aforementioned cases and the case of a planar circular hole having the same area.
