abstract = {In order to study the dynamics of colloidal suspensions
with viscoelastic solvents, a simple mesoscopic model of the
solvent is required. We propose to extend the multiparticle
collision dynamics (MPC) technique--a particle-based
simulation method, which has been successfully applied to
study the hydrodynamic behavior of many complex fluids with
Newtonian solvent--to shear-thinning viscoelastic solvents.
Here, the normal MPC particles are replaced by dumbbells
with finite-extensible nonlinear elastic (FENE) springs. We
have studied the properties of FENE-dumbbell fluids under
simple shear flow with shear rate ̇γ. The stress tensor is
calculated, and the viscosity η and the first normal-stress
coefficient Ψ(1) are obtained. Shear-thinning behavior is
found for reduced shear rates Γ= ̇γτ>1, where τ is a
characteristic dumbbell relaxation time. Here, both η and
Ψ(1) display power-law behavior in the shear-thinning
regime. Thus, the FENE-dumbbell fluid with MPC collisions
provides a good description of viscoelastic fluids. As a
first application, we study the flow behavior of a colloid
in a shear-thinning viscoelastic fluid in two dimensions. A
slowing down of the colloid rotation in a viscoelastic fluid
compared to a Newtonian fluid is obtained, in agreement with
recent numerical calculations and experimental results.},
