Interbubble gas diffusion

Foam Coalescence Coalescence is of two types. The first is the growth of the larger foam bubbles at the expense of the smaller bubbles due to interbubble gas diffusion, which results from the smaller bubbles having somewhat higher internal pressures (Adamson, The Physical Chemlstiy of Suifaces, 4th ed., Wiley, New York, 1982). Small bubbles can even disappear entirely. In principle, the rate at which this type of coalescence proceeds can be estimated [Ranadive and Lemhch,y. Colloid Inteiface Sci., 70, 392 (1979)].

In Section III, we will discuss briefly the phenomenon of interbubble gas diffusion (Ostwald ripening), which has been ignored in our model.
