Three dimensional numerical simulation of combustion and heat transfer in porous radiant burners

In the present study, combustion phenomenon and heat transfer in a three-dimensional rectangular porous radiant burner are numerically studied. Methane-air mixture with five-step reaction mechanism is used to model the combustion process inside the porous matrix. Because of the non-local thermal equilibrium between solid and gas phases, separate energy equations for each of them are numerically solved. Besides, the discrete ordinates method is...
