A two-dimensional quasi-homogeneous reactor model of porous media coupled with chemical reactions via the CFD method is established. The operating range and performance of the reactor under different operating conditions are studied using this model. Taking RP-3 fuel as the research object, using a single temperature model of porous media in Fluent 17.0 software, we add the solid phase energy equation through UDS (User Defined Scalar), and add the chemical reaction heat to the solid phase energy equation through the source term. The effect of key parameters on the ignition process of the reactor and the temperature change of the reactor catalytic bed during the ignition process are simulated. The results show that the temperature of the catalytic bed is uneven during the ignition process of the reactor; the increase of the mole fraction of RP-3 can considerably reduce both the ignition time and the ignition temperature; an appropriate gas velocity exists to enable fast reactor light-off.
