Modelling of immiscible liquid-liquid systems by Smoothed Particle Hydrodynamics.
TL;DR: The SPH model is demonstrated by applying it to a range of model problems with known solutions, including the Young-Laplace problem, confined droplet deformation under a linear shear field, and a droplet falling under gravity through another quiescent liquid.
