Filtration modelling in wall-flow particulate filters of low soot penetration thickness

CFD Simulation of Soot Filtration in Diesel Particulate Filters

Soot emissions from automotive applications can be reduced through on-board diesel particulate filters (DPFs): the filter gets progressively loaded by filtering the soot laden flue gases, thus causing an increasing pressure drop, until an oxidative regeneration is induced by temperature rise. Due to the complexity of the involved phenomena, a fully predictive and detailed mathematical model rep...

Lattice Boltzmann Simulation on Flow with Soot Accumulation in Diesel Particulate Filter

Since diesel exhaust gas has more ambient air pollutants such as NOx and particulate matters (PM) including soot, the special treatment for exhaust emission standards is needed. Recently, a diesel particulate filter (DPF) has been developed to reduce PM in the after-treatment of exhaust gas. However, since the structure of the filter is small and complex, it is impossible to examine the phenome...

Multi-scale interaction of particulate flow and the artery wall.

We discuss, from the perspective of basic science, the physical and biological processes which underlie atherosclerotic (plaque) initiation at the vascular endothelium, identifying the widely separated spatial and temporal scales which participate. We draw on current, related models of vessel wall evolution, paying particular attention to the role of particulate flow (blood is not a continuum f...
