摘要：

A monodisperse liquid foam is allowed to coarsen while subject to a constant flow of liquid. The average bubble size is indirectly monitored by measurement of the velocity of forced drainage waves. After an initial period the average bubble diameter is found to increase with the square root of time. The rate of this increase is a function of the flow rate; coarsening is slower in wet foams. This rate is linked to the variation in the film area in a foam as a function of liquid fraction.
