Abstract

We develop a discrete model for multi-component viscoelastic fluids based on the lattice Boltzmann method. The model newly introduces the kinetics of polymers so that viscoelasticity is included. We perform three-dimensional simulations of a Newtonian drop in shear flow of a viscoelastic fluid in order to investigate the validity of the current model. In the investigation, effects of viscoelasticity on deformation and orientation of drops are evaluated. The simulation results are compared with experimental measurements quantitatively, and they show good agreement with each other.
