Expected, ensemble average values of the o/w surface transport variables for different values of the capillary number, Ca, flow rate ratio, r, and viscosity ratio, . a) Reduced superficial velocity of o/w surface, U_ow,DOF, b) Fraction of o/w surface transport through ganglion dynamics , c) Fraction of o/w surface transport through drop traffic flow,, Arrows indicate increasing Ca values: →10⁻⁸ ≤ Ca ≤ 10⁻⁴ and - - - -> 4 × 10⁻⁷ ≤ Ca ≤ 10⁻⁴.
