摘要: In this study, we investigate the squeeze flow behavior of an upper-convected Maxwell fluid between a sphere and a plate. Based on the Newtonian fluid velocity field, we use the perturbation method to derive analytical expressions for the pressure distribution and normal squeeze force of the sphere-plate squeeze flow, which can be implemented into the contact model for the discrete element simulation of a wet particle system with a Maxwell fluid. Additionally, the sphere-plate case investigated in this paper can be easily transformed into both the plate-plate and sphere-sphere cases, forming a set of complete contact force models with these two cases, thus offering a wider applicability.
