Entropy Generation and Exergy Assessment of Methane–Nitrous Oxide Diffusion Flames in a Triple-Port Burner

A triple-port burner was used in this study, and a numerical simulation employed to investigate the entropy generation rate of CH4–N2O diffusion flames at R id="M2"> ratio = 1 . Here, id="M3"> ratio refers oxidizer flow velocity fuel velocity. In order scrutinize decomposition effect N2O on generation, an oxygen-enriched gas with same nitrogen oxygen as (N-to- id="M4"> O 2 ) CH4–N2–O2 flames. Besides, because could decompose into gas, also studied by CH4–air that were conducted research. The comprises three items including heat conduction, mass diffusion, chemical reaction. As result, different reaction pathways would take part major pathway flames, causing more being produced through intense reactions irreversibility are dominated conduction reaction, which is identical result However, caused thermal decomposition. influences availability
