In this paper, a two-dimensional Stokes flow having particle size distribution ranging from 10 to 50 µm in a rectangular channel is simulated numerically with focus on the hydrodynamic forces. The results show that due to the disparity between the density of the fluid and particles, velocity domain of particles deviates from the fluid velocity domain and this phenomenon occurs significantly for the larger particles. Also, with the increase of Reynolds number, the volume fraction of dispersed phase near the bottom wall of the channel increases either. Compared to similar studies, this investigation employs numerical simulation of microparticulate flow and interparticle hydrodynamic forces with emphasis on the dispersed phase volume fraction in order to present the microchannel flow properties.
