Abstract
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 [3-4].
