A comparison of two mathematical models from two cycle simulation software packages predicting a cold flow and filtration process of a Diesel Particulate Filter (DPF) is studied extensively. Three Cordierite Diesel Particulate Filters (DPF) models, with variations in washcoats (bare, washcoat-only, and catalyzed washcoat), are built and validated to experimental data. The goal is to estimate the values of wall permeability (kwall) and friction loss coefficient (ξ) from the flow bench test and the values of soot permeability (ksoot) from the filtration process. Good agreements are found comparing between experimental data and simulation. The values of those parameters obtained from each software packages show the same trend among all tested DPF samples. However, they are different when comparing cases by cases because of the methodology lies in each mathematical model.
Key words: Diesel Particulate Filter / Wall Loading / Aftertreatment Cycle Simulation
