Abstract
Microchannels are susceptible to blockage by solid particles. Based on the present experiments, aggregation of clusters was observed for flow of liquid with 0.01 volume concentration of polystyrene particles, about 1.5μm in nominal diameter, through a microchannel 15μm high. The phenomenon of interest is the formation and growth of clusters in the flow of a dilute suspension of hard spheres. In general, the clusters initially grow almost linearly in time under various conditions. The spatial distribution and time evolution of clusters along the microchannel have been characterized. The effects of flow rate, volume fraction and channel-height to particle-diameter ratio are discussed as well.
