Abstract

We propose a unified explanation of pattern formation in sheared two-phase viscoelastic fluids that fall within the simple paradigm of interacting soft elastic domains suspended in a less viscous fluid under simple shear flow. Three very different systems are shown to exhibit the same type of shear response, which we relate to the high elasticity of the dispersed phase in the form of an approximate Weissenberg number. The physical mechanism for the formation of this characteristic domain pattern are considered, as is the notion of universality in the shear response of binary fluids with viscoelastic asymmetry.
