Double-layer micro porous media burner from lean to rich fuel mixture: Analysis of entropy generation and exergy efficiency
Porous media burner (PMB) is widely used in a variety of practical systems, including heat exchangers, gas propulsion, reactors, and radiant burner combustion. However, thorough evaluations of the performance of the PMB based on the usefulness of entropy generation, thermal and exergy efficiency asp...
