Abstract
The deformation and breakup in shear flow of an encapsulated drop, in which both the core and shell are Newtonian fluids, were investigated. The equation of motion were solved numerically using a level set method to track interface motion. A phase diagram was presented to define the morphologies produced over a range of capillary numbers and core interfacial tensions. The results show that drops with differing properties can behave similarly under certain flow conditions but quite differently under others.
