Abstract

The dissolution of the droplets of a chlorobenzene and isopropanol mixture in water that filled the Hele-Shaw vertical cell is experimentally studied. The choice of a cylindrical shape for droplets, thus providing only one free (lateral) surface, makes it possible to use the interference method to obtain quantitative characteristics of the studied process. Information on arising flows is obtained by examining the motion of opaque emulsion formed at the interface during the dissolution of a mixture. The interrelation between various mass transfer mechanisms in the droplet as a function of the initial concentration of a mixture and the time of dissolution is discussed.
