Modelling of diesel filters for particulates removal

Original language description

Diesel particulate filter (DPF) is regarded as the most useful technology to reduce particulate matter from exhaust gas of a diesel engine, with filtration efficiencies in excess of 90%. Exhaust gas entering the channel is forced to flow through the ceramic porous walls into the adjoining cells and thus leaving the particulates behind. The collected particulate matter inside the trap has to be periodically oxidized to regenerate the DPF. We have developed a transient spatially 2D model of the filter, soot deposition and its regeneration. The momentum, mass and enthalpy balances of the gas and the solid phase were employed in the model including the description of heat conduction, diffusion in the solid phase and complex soot combustion kinetics. Detailed kinetics of soot combustion is considered: combustion by O2?both the thermal initiated one and the catalyzed one and the oxidation by NO2. The results of simulations include the prediction of development of concentrations, temperature,
