Abstract

The drainage flow of the continuous phase and coarsening of the dispersed phase was used to determine the evolution of a foam. The foam drainage for the gases of large solubilities were strongly influenced by coarsening. The acceleration of drainage and shortening in lifetime of foam was caused by the strong coarsening. Due to the competing effects of enhanced liquid permeability and reduced gas permeability in strongly coarsening foams the drainage times was observed independent of self-limiting drainage.
