摘要: Present study has been conducted to see the relative effects of adding N: fuel-side and air-side on flame structure, soot formation NOx emissions. Experiments were carried out ascertain what degree chemical kinetics and/or molecular transport can explain differences in emission by studying laminar diffusion flames. Direct photograph was taken structure. CARS techniques used get temperature profiles. And spatial distribution could be obtained PLII method. CHEMKIN code also estimate global residence time predict emissions at each condition. Results from these studies indicate that dilution is more effective than view However, shows greater effectiveness over formation. turbulent mixing heat transfer problems thought considered practical applications.
