In the process of optimum DPF system design, one has to take into account the specific needs and limitations in each specific engine application. Modeling aims at reducing development time and cost by replacing a large part of the testing work with simulations.

LAT carries a long tradition in DPF research and modeling in close co-operation with industrial partners all over the world. More than 50 scientific articles and 10 PhDs have been authored by LAT on DPF related subjects.

The modeling approach is application-oriented and supported by experimental data, produced in-house or supplied by industrial partners. State-of-the-art numerical techniques are used to compute the transient DPF performance in a 2-D axi-symmetric domain, taking into account the complex heat transfer and reaction phenomena with or without catalytic assistance.

CFD simulations are used to access the effect of inlet cones on filter performance.

Special attention is given to small scale phenomena taking place in the filter. To this end, the model is supported with microscale experiments on single channels.
