Comparison of the model with experiments. (A) Droplets of different sizes create self-similar multiple emulsions (i–iii), except that one extra small droplet fits into the largest mother droplet (iii), simulated in iv. (B) The radial position of layers as a function of time reveals a stretched exponential rather than a diffusive (Epstein–Plesset theory) time course for the immiscibility front. (C) Layer spacing decreases toward the center of the droplets for all droplet sizes in excellent agreement with the model. Rescaling the spacing by the layer radius gives a constant ratio , shown in the Inset, as a signature of self-similarity. (D) Consecutive radii of the layers collapse onto a straight line for all droplet sizes, whose slope gives the ratio of lengths in C. (E) Adding ethanol to the continuous phase decreases and gives rise to a finer spacing of the layers . This effect is well captured by a linear correspondence with the leakage rate in the model, shown in the Inset.
