A chapter in Mathematical Modeling, Simulation, Visualization and e-Learning, 2008, pp 51-61 from Springer

Abstract: Catalytic converter in an automobile's exhaust system is made up of a finely divided platinum—iridium catalyst (i.e.forming a porous matrix)and provides a platform for exothermic chemical reaction where unburned hydrocarbons completely combust.In this paper, the steady-state solutions of a strongly exother-mic reaction of a viscous combustible fluid (fuel)in a catalytic converter-modelled as a cylindrical pipe filled with a saturated porous medium under Arrhenius kinetics, neglecting reactant consumption, are presented.The Brinkman flow model is employed.Having known the velocity distribution, the nonlinear energy equation is solved using a perturbation technique together with a special type of Hermite—Padé approximants and the important properties of the temperature field including bifurcations and thermal criticality are discussed.
