Analysis of limiting models of a Diesel Particulate Filter (DPF) provides insight on its design and operating conditions. Analytical expressions for predicting the filtration velocity; pressure drop; filter heat-up time and speed and width of the temperature front in a DPF are presented. A more uniform filtration velocity with a lower pressure drop can be obtained by either decreasing the inlet velocity; increasing the channel hydraulic diameter or by increasing the DPF aspect ratio (D/L) under constant DPF volume and flow rate. The DPF heat transfer properties depend on the heat capacitance ratio (σ) and the effective heat Peclet number (Peh; e) as well as on the hydraulic parameters. The speed of the temperature front can be increased by decreasing the DPF substrate thickness and volumetric heat capacitance. Higher value of Peh; e decreases the DPF front heat-up time and sharpens the temperature front. When Peh; e is smaller than 8; the temperature front covers the whole DPF length. When it is larger than 128; a sharp front forms covering less than 25% of the DPF length. The effective heat Peclet number attains a maximum value at an intermediate inlet velocity and channel hydraulic diameter. Increasing the DPF aspect ratio (D/L) under constant DPF volume and flow rate can help achieve two important design targets; low pressure drop and a wide temperature front. © 2013 Elsevier B.V;
