Expected, ensemble average values of the reduced mechanical power dissipation, W, and its partition into the individual interstitial, constituent flows, for different values of the capillary number, Ca, flow rate ratio, r, and viscosity ratio, . Arrows indicate increasing Ca values: →10−8 ≤ Ca ≤ 10−4 and - - - -> 4 × 10−7 ≤ Ca ≤ 10−4.
