=9 m/s, and vf=14 m/s are displayed in Fig.4. Findings from this figure are: 1) When the fuel flux is small, as shown in Fig.4(a), the combustion is achieved in high oxygen. In plane-ZY, the higher...-XY. The whole temperature distribution is: TⅡ＞TⅠ＞TⅢ＞TⅣ. 2) When the fuel flux is suitable, as shown in Fig.4(b), the complete combustion gradually becomes low oxygen combustion, which makes the high......
