Building on these concepts of force chains and translocation ∆P, we can use the critical ∆P to estimate the force required to disrupt a clog or prevent it from forming. This critical ∆P represents a force divided by the cross sectional area of all the channels. The channel depth is ∼10 µm throughout the device, channel width narrows from 40 down to 4 µm. There are 165 channels which are each subject to ∆P due to their arrangement in parallel. If ∆P crit ≈ 1000 mbar balances the force across a single clog spanning the entire channel width, this suggests that particular clog can sustain ≈ 4 -40 µN. This estimate is most appropriate if there exists a single clog along the length of a channel. The presence of multiple discontinuous clogs along the flow direction would reduce this estimate. Still, 1µN is the same order of magnitude as that observed in a jamming of a quasi 2-D emulsion . However, this estimate is an upper limit, acknowledging that the pressure losses in the flow direction are affected by the presence of the clogs. In narrower regions of the channels, where bridging is possible, existence of a critical ∆P may represent disruption of a simultaneous bridging event. However, in wider regions of the channels, where clogging may be facilitated by a single adhered particle, this pressure may represent prevention of the final particle or particles to complete the clogging arch.
