dc.description.abstractThe aim of this thesis work was to establish a kinetic and heat transfer model for the Diesel Oxidation Catalyst (DOC) using GT-Suite. The kinetic model was calibrated using a transient Part Load Map (PLM) driving cycle. The inhibition functions of the reactions were tuned to obtain a good curve fitting of reaction species. When a different drive cycle was applied, the model predictability was poor. The result demands a requirement for better heat transfer modelling. Adetailed external Heat transfer model was set up for this purpose. The results were better and the model was found to account for thermal mass variations in the system. The flow along the DOC was non-uniform, a 2 DOC model was established to account for the unequal inlet flow split and improved thermal mass understanding of the model. The results of the 2 DOC model however were inferred to be the same as 1 DOC. A discussion of results and a future outlook are presented.
