This paper introduces the problems related to particle motion in viscoelastic fluids and emphasizes the importance of lateral equilibrium position of particles, interaction and aggregation of multiple particles, chain structure formed by multiple particles, and motion of non-spherical particles. Future research should focus on addressing these issues.
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.
