Numerical Simulations of Axisymmetric Stokes Flow in Multi-phase fluids ABSTRACT: The goal of this work is to study the evolution of double emulsions exiting from a microfluidic nozzle using numerical simulations. Laboratory experiments have shown that in certain cases the drops break up as they exit, thus releasing the inside phase to the outside, with applications to drug delivery through atomized sprays, food processing and cosmetics. The flow is well described by the axisymmetric Stokes Equations. We derive the coupled boundary integral equations for the flow velocity, address several of the numerical issues in the evaluation of the singular and near-singular integrals, and conclude with numerical results for the full simulation.
