Experimental Studies of Diesel Particle Filtration
… performance of the DPF typically treat deep-bed filtration and cake filtration as two distinct regimes. Since the deep-bed filtration stage causes the rapid initial increase in exhaust back pressure as a clean DPF is loaded, it is of significant advantage to engine operation to minimise particle …

FLUID FILTRATION FROM CAPILLARY NETWORKS (MICROCIRCULATION, MATHEMATICAL MODELING).
A mathematical model has been developed which describes the fluid exchange from a capillary network of realistic topology, and calculates the spatial distribution of extravascular pressure. In this model, the capillaries are represented by a superposition of sources and sinks, resulting from a …
