Suspension clogging fronts in a leaky pipe

ORAL

Abstract

A particle suspension flowing through a leaky microfluidic channel forms clogs that propagate backwards against the incident flow direction indefinitely. We study the speed and shape of clogs in such situations and show how we can control them. Further, we show that the particulate order in the clog can be controlled by tuning the geometry of the leaky walls. Time permitting, the implications of this for flow through parallel channels will also be addressed.
