Abstract：Based on the experimental data of a certain ship engine methane reactor,the inertia resistance coefficient and viscosity resistance coefficient of porous media fluid are fitted.A reactor model is established using STAR-CCM+ and simulations are conducted to study the uniformity of the internal flow field and pressure drop in the reactor.The results show that when the fluid inertia resistance coefficient is 340.82 kg/m4 and the fluid viscosity resistance coefficient is 1 437.27 kg/(m3·s),the simulation model achieves the best fitting result.The pressure drop in the reactor is mainly caused by the pressure drop in the catalyst layer.The uniformity of exhaust gas flow rate at the catalyst inlet reaches 97%,which indicates a uniform distribution of exhaust gas.The temperature of catalyst exhaust gas affects the average flow rate,causing a certain deviation between the experimental pressure drop and the simulated pressure drop.
