Abstract
Fundamental combustion characteristics of lifted flames at high-temperature oxygen combustion conditions were investigated experimentally and numerically. Two types of the flame structures for lifted flames were identified by experimental flame images captured by a still camera with a CH band-pass filter as well as computations. One could be classified to be a tribrachial lifted flame, and the other could be classified to be mild combustion. In 2-D computations, the reaction zone was formed beyond the stoichiometric line at mild combustion conditions.
