A penalty immersed boundary method for viscoelastic particulate flows
Journal of Non-Newtonian Fluid Mechanics(2018)
摘要
•A numerical method is introduced to investigate particulate viscoelastic fluid.•The method is tested by a convergence study.•The effect of the elasticity number and channel wall is presented.•A chain is formed with multiple particles falling in an Oldroyd-B fluid.
