A code based on the distributed Lagrange multiplier/fictitious domain method (DLM) is used to study the motion of a sphere sedimenting in a viscoelastic liquid near a vertical wall. The viscoelastic liquid is assumed to be shear thinning and modeled by a shear-thinning Oldroyd-B model. Our simulations show that when the Deborah number based on the sphere… (More)
