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.
