Tapered geometries are typically found in nozzles -for example, in 3D printers, injectors and extruders . It could summarize flow dynamics in systems where the cross-sectional area decreases along the flow path such as in multi-stage filtration systems and blood circulation. Also, investigating clogging in gently tapered channels facilitates measurements of clog formation over a range of particle size to pore width ratios. This work describes such in a system of 165 parallel tapered channels. The channels are all connected to one inlet reservoir, and each tapers gently from inlet to outlet at a constant angle. The channel inlets are 10 particle diameters wide while the outlets are the same size as the particles. Thus, the particles do not escape the channels.
