ABSTRACT

Based on the concept of local thermal equilibrium an exact solution is reported to investigate effects of a porous segment at the outlet of a high-temperature one-dimensional duct modeled as an industrial furnace. Since the enthalpy of a high-temperature gas is converted to thermal radiation by means of this porous segment, thermal efficiency increases. The two-flux method is taken into account for this problem.
