The Diesel Particulate Filter (DPF) modeling has been used to predict the pressure drop, deposited soot mass and regeneration of DPF. But the prediction of DPF behavior requires the experimental data in which the most important parameter is hydrodynamic resistance factor. In this research, it was obtained as a function of particle's approach velocity. Also, the relations between the pressure drop and deposited soot mass were obtained experimentally.
In order to investigate the characteristics of soot loading and oxidation behavior within DPF, a partial flow system was designed which can be used to measure important parameters at the same temperature and flow rate with those of the single channel DPF.
From the experiments, it was observed that the pressure drop increased with increasing particle's approach velocity at the constant temperature, and temperature variations had no effects on the normalized pressure drop with respect to flow rate in the temperature range between 260°C and 340°C. It implies that the pressure drop across DPF is affected by soot mass and can be used as a direct measure of deposited soot mass. In addition, the hydrodynamic resistance factor was found to be an exponential function of approaching flow velocity.
