Abstract
The dynamics of foam drainage (free, forced and pulsed) is monitored b y the determination of local liquid density using a vertical array of capacitors. Liquid profiles are obtained for various drainage experime nts. The merging of two solitary waves is in good agreement with theor etical predictions. Such capacitance measurements offer a convenient p ractical technique for characterising the more general properties of n on-conducting foams.
