Abstract
The burning intensity of inverted flames has been studied by using spontaneous Raman scattering technique. The results substantiate the general concept of the influence of flame stretch and preferential diffusion on the flame temperature. Specifically, it is found that the measured flame temperature of inverted flames is higher (lower) than the adiabatic flame temperature for mixtures whose effective Lewis number is smaller (greater) than unity, and that this behavior is qualitatively opposite to that observed for Bunsen flames whose curvatures are opposite to those of the inverted flames. It is further demonstrated that heat loss to the stabilizing rod appears to have very little influence on the flame behavior, including flame stabilization and blowoff, and suggested that flame curvature could exert a stronger influence on these phenomena.
