Abstract
Recently, Indian government enforces stringent control standards for automotive emissions in order to minimise pollution and keep the environment green. To confirm these emission norms, new advanced technologies have been developed in the automotive emissions after treatment systems market. Diesel oxidation catalyst is one of the important contraptions which play a major role in reducing CO and unburned HC emissions. By employing CFD software, the flow properties of catalytic converter can be analysed. This helps to optimise the surface area of DOC, and the effective reaction area is utilised for oxidising the unburned hydrocarbon and carbon monoxide of engine exhaust gases. In the present work, 0.8-litre DOC has been modelled in CATIA V5 software, and CFD analysis was executed by ANSYS CFX software. The pressure drop has been compared by varying the cell density and wall thickness. Finally, the results are compared and the parameters of substrate which give optimum pressure drop are established and concluded. The novelty of the present work is that wall thickness of the porous media substrate, which is in mill inch, has been considered to find out the pressure drop. Calculated pressure drop is verified with engine test bed pressure drop experimental data, before concluding the results.
