Abstract: In this paper velocity field and settling distribution of micro-particles in a dilute suspension in low-Reynolds-number poiseuille flow in a microchannel is experimentally investigated using microscopic image analysis. An effective technique is applied to manipulate single particle tracking in order to determine the controlling parameters on transportation and settling of micro-particles in microchannels. The results show that the velocities of dispersed phase are affected by the hydrodynamic properties and this velocity deviation can be significant when the hydrodynamic coupling between particles and channel walls is considerable. Increasing the Reynolds number would result in decrease in total number of particles settled on the bottom wall of channel.
