The goal of this work is to investigate the evolution of double emulsions exiting from a tapered nozzle using numerical simulations. Laboratory experiments have shown that in certain cases the drops break as they exit, thus releasing the inside phase to the outside. Important applications include drug delivery through atomized sprays, inkjet printing, food processing and cosmetics. The flow is well described by Stokes Equations. In this talk I will derive the coupled boundary integral equations for the flow velocity,and focus on several of the numerical issues that arise in evaluating the resulting singular and near-singular integrals. I'll conclude with some numerical results for the full simulation.
