The dynamics of dense stabilized emulsions present a rich phenomenology including chaotic emulsification, non-Newtonian rheology, catastrophic phase inversion and aging dynamics at rest. Macroscopic rheology results from the complex droplet microdynamics, and in turn, droplet dynamics is influenced by macroscopic flows via the competing action of hydrodynamic and interfacial stresses, giving rise to a complex tangle of elastoplastic effects, diffusion, breakups, and coalescence events. This tight multiscale coupling, together with the daunting challenge of experimentally investigating droplets under flow, hindered the understanding of dense emulsions dynamics. In this talk, we will present recent results from fully resolved 3d numerical simulations and experiments, capable of resolving the shape and dynamics of individual droplets, along with the macroscopic flows. We will discuss some key aspects of the flow physics of dense emulsions, from the formation via chaotic emulsification, the way they flow, including their loss of stability via catastrophic phase inversion, and their dynamics in the aging regime.
