Fig. is a tiled and analyzed image of the clogged 165 microchannels for a flow test conducted with ∆P = 700 mbar and φ = 0.10%. The image demonstrates the presence of multiple distinct clogs in each channel, indicated by bright spots or streaks in the image. For each clog, the width w, length l and centroid (x, y) are measured (Fig. ). See Fig. in SI for tiled images of clogged channels from other conditions of ∆P and φ .
