A liquid transport system utilizing encapsulated liquid drops is developed. An experimental apparatus for the sequential production and the self-recovery of encapsulated drops is designed using effectively the functions of the buoyancy-driven motion and the breakdown phenomena of encapsulated drops in liquid-liquid-gas systems. As the first step to investigate the flow characteristics of encapsulated drops in the apparatus, the mean diameter, the shell thickness and the production frequency of encapsulated drops are measured for the wide range of the flow conditions and the liquid properties. The formation patterns and the behavior of encapsulated drops are also observed in detail. The results obtained here would provide the fundamental knowledge for designing the high performance heat and mass exchangers using liquid-liquid-gas systems.
