Abstract:

The equilibrium shape of a liquid or gas drop Phase 1 of density d1 at a horizontal interface separating two fluid phases Phases 2 and 3 of densities d2 and d3 can be calculated from the principles of capillarity. In the most general system these calculations are extremely complicated, and solutions have been obtained only for some special cases very small drops systems with d1 d3 and very large drops when d3 d1 d2. When d1 d3 there is a critical drop size above which the drop cannot be supported by the interface and ascends to the top of the system. This is illustrated with the model system of an infinitely long cylinder at an interface. The same model system is used to illustrate the experimental observation that a cluster of two or more drops, each of which is below the critical size, may cross the interface. Author
