25 Years of DPF Simulation: the Standard Model Revisited

Athanasios  Konstandopoulos, APT Lab, CPERI/CERTH

We re-formulate the standard Diesel Particulate Filter (DPF) simulation model, based on solving the relevant mass, momentum and energy transfer balance equations in their perimeter averaged form, in a single channel of the DPF with the goal (i) to improve it in a number of areas related to the treatment of relevant transport and reaction phenomena and (ii) to extend its applicability to more complex physicochemical phenomena without sacrificing the easiness of its implementation or its computational performance. As a result a self-consistent and computationally fast, Revised Standard Model of DPF simulation is obtained, which should be more useful for the design and application engineering of future DPF systems.
