The results presented in this study demonstrate the significance of confinement geometry on clogging processes. Understanding features of suspension flow through tapered channels can help in the design of filters with extended lifespans. Also, a tapered geometry summarizes flow and clogging behavior in systems where the flow cross section narrows over multiple length scales. Examples are found in blood circulation, printer nozzles, and multistage filters designed to trap even the smallest suspended particles. In particular, the microfluidic device mimics systems where suspension flow is distributed from one source into multiple tapered streams.
