Coalescence Conditions for Bulk Nanobubbles

Abstract

The coalescence of two nanobubbles with substantially different radii is considered. Studies of this problem have practical significance, because coalescence is an undesirable process (the nanobubbles lose their unique properties after enlargement). An energy-based approach is used with a simplified model of charged nanobubbles to demonstrate that bulk nanobubble coalescence can take place at specific values of surface charge density, concentration, and radius ratio, in contrast to the case of surface nanobubbles.
