Abstract
A discussion is presented of the applicability of well-established theories of interface-reaction-controlled Ostwald ripening of second-phase precipitate distributions, and of the evolution of grain distributions in polycrystalline materials, to the problem of foam evolution by interbubble gas diffusion. Two limiting cases are developed in detail: evolution of a narrow size distribution of foam bubbles, and characteristics of a bubble distribution at asymptotically large times.
