Évaporation de gouttes près du point critique : influence de la tension superficielle sur les conditions d'équilibreS. Préau and R. Prud'homme

The influence of surface tension on droplets in equilibrium in their vapour is investigated here. Equilibra cases for a pure body and for a binary mixture are successively examined by means of classical thermodynamical arguments, without mentioning the equation of state. It appears that the surface tension produces a difference in relation to the plane case, which is, as a first approximation, of the order of the ratio between the molecular diameter and the droplet's one.
