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...
متن کاملCFD 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...
متن کاملEffect of Pore Structure on Soot Deposition in Diesel Particulate Filter
Nowadays, in the after-treatment of diesel exhaust gas, a diesel particulate filter (DPF) has been used to trap nano-particles of the diesel soot. However, as there are more particles inside the filter, the pressure which corresponds to the filter backpressure increases, which worsens the fuel consumption rate, together with the abatement of the available torque. Thus, a filter with lower backp...

15 صفحه اولLattice Boltzmann simulation on continuously regenerating diesel filter.
To reduce particulate matter (PM) including soot in diesel exhaust gas, a diesel particulate filter (DPF) has been developed. Since it is difficult to observe the phenomena in a DPF experimentally, we have conducted a lattice Boltzmann simulation. In this study, we simulated the flow in a metallic filter. An X-ray computed tomography (CT) technique was applied to obtain its inner structure. The...
