Abstract

The Flame length of $CH_4$ with the Oxidizer of air and $O_2$ has been measured respectively for the nozzle diameter of 1.6mm, 2.7mm, 4.4mm and 7.7mm. In all $CH_4$ flame on oxidizer of air and $O_2$. the flame length was independent of the initial jet diameter, dependent only on the flowrate in laminar flame regime, and in turbulent flame dependent on the initial jet diameter. Using correlation equation of Delichatsios, the flame length has been expected exactly for $CH_4/air$ flame, but has been underestimated for $CH_4/O_2$ flame. This paper has proposed correlation equation of $CH_4/O_2$ flame.
