| Description | Forced non-coalescence between two bodies of the same liquid may be achieved by a variety of means, all of which provide relative tangential motion of the adjacent free-surfaces. This motion serves to provide a lubricating film of the surrounding gas to the gap which prevents the liquid surfaces from coming into contact. One means of forcing non-coalescence is to use thermocapillarity to drive the lubricating film by having the liquids at different temperatures. This paper will examine a number of scenarios of non-coalescence behavior, both qualitatively and quantitatively, and describe some envisioned applications of the phenomenon which may have relevance in both microgravity and terrestrial environments. |
