Modeling of the influence of matrix elasticity on coalescence probability of colliding droplets in shear flow

摘要: The theory of shear-flow-induced coalescence monodisperse Newtonian droplets in and viscoelastic (described by the Maxwell model) matrices has been derived. Changes flattening during are considered. Calculated dependences on system parameters probability, Pc, that droplet collision is followed their fusion for systems agree qualitatively with Rother–Davis [Phys. Fluids 13, 1178–1190, (2001)]. Values Pc a certain set substantially affected model used to describe mobility interface.
