Abstract

Diesel oxidation catalytic converters (DOCs) offer a promising solution to reduce diesel exhaust pollutants. In order to improve the thermal management in DOCs, active flow control strategies have been introduced for several years. However, the performance of DOCs needs to be verified by modeling simulations and experimental studies prior to application of these strategies. In this thesis, a series of modulated dynamic models were developed using SimulinkRTM to better understand the heat transfer mechanisms of a catalyst. The simulation results were validated by the reference experimental data collected in the Clean Diesel Engine Laboratory (CDL) at the University of Windsor. The potential of the active flow control in DOCs was demonstrated, because a better thermal management realized by active flow scheme leads to more energy efficient diesel after-treatment. The United States and the Japanese diesel emission test cycles engine data were also used to verify the developed thermal models.Dept. of Civil and Environmental Engineering.
