We performed Direct Numerical Simulation (DNS) of an exothermic gas-phase reaction under laminar flow condition in a 2-D packed bed reactor with random distribution of cylindrical particles of 2.9mm diameter. The reaction used in this work is of Arrhenius type between Ethylene and Oxygen with Ethyle...
