The incomplete regeneration of diesel particulate filter may cause a local build‐up of the soot on the partially regenerated areas during next filtration cycle. This may be one of reasons causing the melting of the ceramic filter during regeneration. In this paper, we investigated several situations at which the particulate matter was partially regenerated. The simulations illustrated that at stationary feed conditions, the influence of nonuniformity of soot loading on the peak temperature rise was less important. When regeneration was conducted at transient feed conditions, the peak temperature attained under the condition of uneven soot distribution along the channel, especially more soot accumulated near the end of the diesel particulate filter, was much higher than that attained under the condition of even soot distribution inside the channel. © 2013 Curtin University of Technology and John Wiley & Sons, Ltd.
