Abstract

A numerical study of combustion and multimode heat transfer in porous radiant burners is performed. Burner characteristics such as flame speeds, radiant outputs and efficiencies are investigated using a one-dimensional conduction, convection, radiation, and premixed flame model. The porous medium is assumed to emit, absorb, and scatter radiant energy. Non-local thermal equilibrium between the solid and gas is accounted for by introducing separate energy equations for the gas and the solid phase. Combustion is described by a one-step global mechanism. The effect of the optical depth, scattering albedo, solid thermal conductivity, upstream environment reflectivity, and interphase heat transfer coupling on the burner performance are studied.
