Surfactant Concentration and Transition Foam-Quality

Foam coarsens above a certain “transition gas fractional flow” in porous media. Experimental data show that for a specific porous medium, the transition gas fractional flow rises rapidly with surfactant concentration at low concentrations and approaches a constant value at high concentrations. We present the results on the relationship between the surfactant concentration, the foam-bubble radius, and the transition gas fractional flow.
