Abstract

Widespread market application of diesel particulate filters (DPFs) has been accompanied by the introduction of new filter materials and configurations in terms of cell density, wall thickness, pore size, porosity, catalyst coatings etc. Given this state-of-affairs, materials development, DPF design, system integration, regeneration control strategy optimisation and ash ageing assessment, based on a traditional design of experiments approach, become very time consuming and costly, due to the high number of tests required. This provides a privileged window of opportunity for the application of simulation tools. DPF behaviour depends strongly on the coupling of phenomena occurring over widely disparate spatial and temporal scales and the simulation approach must recognise and exploit these facts.
