Scalings for droplet sizes in shear-driven breakup: non-microfluidic ways to monodisperse emulsions. (English) Zbl 1232.76013

Summary: We review studies of a drop of viscous liquid, suspended in another liquid, and undergoing breakup in an impulsively started shear flow. Stokes flow conditions as well as the effects of inertia are reported. They reveal a universal scaling for the fragments, which allows one to use sheared emulsions to produce monodispersity as an alternative to microfluidic devices.
