抄録
内容記述 Using an axisymmetric swirl-type burner with eight inlet slits, the effects of rotation on the structure and characteristics of tubular flames have been investigated for lean methane/air mixtures. Results show that with increasing intensity of rotation, (1) the flame diameter increases and the thickness of the luminous zone decreases, (2) the fuel concentration at extinction decreases, i.e., the stable region expands, (3) the radical temperature distribution becomes an M-shaped profile, and the maximum temperature Tf increases while the local minimum temperature Tc at the center decreases, and (4) the values of Tf and Tc vary in a complicated manner in the axial direction. These results are almost consistent with those of our previous experiment, and hence, it is confirmed that the flame structure and the flame characteristics are affected by rotation. As for these phenomena, several mechanisms such as pressure diffusion, radiative heat loss, viscous energy dissipation, and energy recirculation including diffusion of radical species have been proposed. The present experimental results provide the first, basic information on this practically important phenomenon, i.e., the extension of flammable range by rotation.
