Abstract
Simulations with Lattice Boltzmann method are conducted for particulate suspension in a plane channel flow at low and moderate Reynolds numbers to investigate blood cell behavior in microvascular flows. The simulation results for three kinds of hematocrit indicate existence of an important relationship between the Reynolds number and the variance of the particles. When the hematocrit is small, it is found that the particles are concentrated between the centerline and the wall, that is, Segré-Silberberg effect appears. As the hematocrit becomes larger, on the other hand, this effect disappears and the variance of the particles is increased. In the case of an inelastic collision, the particles which flow near the wall are increased in comparison with the case of the elastic collision.
