Equilibrium shapes for immiscible drop systems
by Michael Neeson
Abstract: When a drop and a bubble, or two immiscible drops coalesce, they form a compound body composed of two independent, but conjoined fluids. The shape of this body is controlled by the interfacial tensions within the system, and if immobilised on a solid surface, can become complicated. In this talk I will use a range of micron-scale mixed systems to demonstrate the geometries available to such fluid bodies, and the thermodynamic reasons for their equilibrium shapes.
