The influence of shear thinning on drop deformation is examined through a numerical simulation. A two-dimensional formulation within the scope of the boundary element method (BEM) is proposed for a drop driven by the ambient flow inside a channel of a general shape, with emphasis on a convergentdive
Drop breakup is an important part of the study of polymer blending. During mixing, large domains of fluids are stretched and broken up into smaller droplets. To obtain a good dispersion of a multiphase system, the size and location of the suspended phase domains need to be optimized. It was seen tha
## Abstract This paper reviews the dispersion mechanisms in viscoelastic systems under relatively high shear rate conditions. In particular, two nonβNewtonian deformation and breakup mechanisms were revealed by flow visualization in a transparent Couette shearing setup. The first one is the dispers
