| Abstract | Coalescence or fusion of two drops or bubbles is a phenomenon that has been investigated in some detail for freely suspended drops or bubbles. However, little is known about sessile conditions when drops or bubbles are on a substrate. Here, the three phases line of contact (solid –liquid –vapor) can play a very important role in the dynamics of relaxation. As bubbles do not, in general, wet a solid (though there are noticeable exceptions, especially during the out of equilibrium conditions of boiling [1-2]), we focus here on sessile drops that present a finite contact angle with the substrate (partially wetting regime). In this lecture, we would like to show how rich and important is the phenomenon of coalescence of sessile drops when dealing with phase transition, and how coalescence dynamics can be limited by the contact line dynamics. 1.
