Description
A deep understanding of the dynamics and rheology of suspensions of vesicles,
cells, and capsules is relevant for different applications, ranging from soft
glasses to blood flow [1].
I will present the study of suspensions of fluid vesicles by a combination of
molecular dynamics and mesoscale hydrodynamics simulations
(multi-particle collision dynamics)
in two dimensions [2], pointing out the big potential of the numerical
method to address problems in soft matter. The flow behavior is studied
as a function of the shear rate,
the volume fraction of vesicles, and the viscosity ratio between inside
and outside fluids. Results are obtained for the interactions of two vesicles,
the intrinsic viscosity of the suspension, and the cell-free layer near
the walls [3-5].
