Particle flows underlie many regulatable phenomena at multiple length scales, such as pedestrian traffic, ion channel flux and information flow. Tuning the system parameters produces a myriad of interesting and unexpected behaviour, notably intermittent dynamics. This thesis presents and analyses three distinct models systems motivated by these phenomena : 1) Analytical models of particulate flow through 1D single channels, as well as coupled and uncoupled channel bundles, with a limited carrying capacity. The stochastic dynamics is studied using queuing theory and regeneration techniques. 2) Finite sized, soft particles driven through a 2D channel, with a single or double constriction are studied using overdamped brownian dynamics simulati...
