| 内容記述 | In this study, we simulated the combustion field in a triple port burner. There are four flame configurations, consisting of attached flames, inner attached/outer lifted flames, inner lifted/outer attached flames, and twin lifted flames. Focusing on the transition process of these flames, the flame behavior and flow field were investigated when the external air flow velocity was increased at constant internal air flow and fuel flow velocities. Except for the attached flame, when the flame is lifted, the axial velocity toward the leading-edge flame gradually decreases downstream, takes its minimum, and then increases very rapidly. This minimum velocity corresponds approximately to the burning velocity of the leading-edge flame. Since two flames are formed in the triple port burner, the inner or outer flame is affected by the other flame located more upstream. Due to the thermal expansion of the upstream outer flame, the downstream inner flame is pushed inward. Since the flame is stabilized at the position where the burning velocity of leading-edge flame and the incoming flow velocity are balanced the axial velocity toward the leading-edge flame is important to discuss the transition of flames. The inner flame re-attachment is caused by the velocity change toward the leading-edge flame. As a result, the unique flame behavior of flip-flop between inner and outer flames occurs. | |||||
