A Level Set method for bifluid flows in Microfluidics is presented. After a stability analysis which conducts to a restrictive stability condition on the computational time step due to surface tension, we introduce a splitting to shorten simulation times. Numerical results of these curvature-driven flows are in good agreement with physical experiments and are used to explore mixing processes inside micro-droplets.
