Foam Injection into horizontal cells with channels of different openings



This paper discusses experimentally the advance and distribution of preformed,
wet aqueous foam ow when it is injected into a horizontal rectangular
cell with dierent transversal opening channels. Speeds of the simultaneous
foam fronts in each channel were obtained experimentally. The
relationship between bubble size and the opening of the channel, the apparent
viscosity and the friction factor were obtained with experimental data.
Experiments were performed under three dierent injection pressures. The
diversion of the foam ow into the transversal channel was also studied. With
these experiments we show that the foam ow stream is aected by sudden
changes in the geometry.
