Deformation behavior of a composite drop in a simple shear flow

The hydrodynamics of disperse liquid media attracts increased attention, first of all, owing to their numerous applications in various industries (chemical, medical, pharmaceutical, processing of polymers, etc.). The theoretical analysis of such systems is based on studying the dynamic behavior of an isolated drop in a flow for determining the strain, orientation, and stability of the drop in various flow modes. To date, an extensive body of experimental data on the mechanisms of deformation and breakup of homogeneous drops has been accumulated [1-6]. However, the hydrodynamic behavior of composite drops containing one or several internal inclusions (cores) remains little studied. At the same time, such objects have a diversity of applications: from increasing the impact resistance of mixed polymer composites to targeted drug delivery [5, 6]. Therefore, the comprehensive investigation of composite drops is of fundamental and practical interest.
