On the some issues of particle motion in the flow of viscoelastic fluids

Particle motion in confined shear flow of viscoelastic fluids is very common in nature and has a wide range of applications. Understanding and mastering the motion characteristics of particles in viscoelastic fluids has important academic value and practical significance. In this paper, we first introduce the related equations and characteristic parameter, and then emphasize the following issues: the lateral equilibrium position of particle; interaction and aggregation of multiple particles; the chain structure formed by multiple particles; and the motion of non-spherical particle. Finally, some unresolved issues, challenges, and future research directions are highlighted.
