Abstract

We examine the influence of shear and elongation on the deformation of a drop as it is driven by the ambient flow in a convergent/divergent channel. Viscoelastic fluids are considered, and a boundary-only formulation is implemented that requires the solution of two simultaneous integral equations on the drop/fluid interface and channel wall. Although the formulation allows the examination of the influence on drop deformation of an array of flow parameters such as viscosity, interfacial tension and elasticity, only the latter is investigated in the present work. 1 Introduction Recently, the BEM has been extended to include the motion of a drop in the vicinity of a plane wall, a deforma
