Abstract

The article presents the results of exhaust gas flow simulation by three configurations of a ceramic support placed in the engine exhaust system. The carriers differed in the cell density parameters along the entire length of the filter. A filter with a fixed CPSI (Cell per Square Inch) parameter, a filter with two different cell densities and a triple support were tested. For each element of the filter, boundary conditions have been introduced, which define the nature of the flow and define the type of surface of a given element. The composition of the exhaust gases whose flow is simulated was also determined. The initial conditions of the simulation include data on pressure, temperature and velocity. AVL Fire Aftertreatment was used to carry out the simulation. The program is a leading tool for CFD simulation in the field of internal combustion engines.
