Besides steric effects and surface interactions, channel geometry also significantly impacts the rate and pattern of clogging by suspended particles . In pores with parallel walls, clogs grow continuously from their points of inception, leading to a linear decay of flowrate with time . Although increasing the entrance angle of approach to a pore can decrease clogging rates, it does not alter the continuous nature of clog growth . However, in pores that gently taper over multiple length scales in the flow direction, flowrate decays much more gradually with time . This results from the discontinuous growth of clogs: the growth of a downstream clog ends when a new clog is initiated immediately upstream. It shows the nature of clog formation and growth determines the details of subsequent decays in flowrate.
